Because Moose roles serve many different masters, they usually provide only the least common denominator of functionality. To empower roles further, more configurability than -alias and -excludes is required. Perhaps your role needs to know which method to call when it is done processing, or what default value to use for its url attribute. Parameterized roles offer a solution to these (and other) kinds of problems.

"require EXPR" only accepts Class/Name.pm style module names, not Class::Name. For that, this module provides "load_class 'Class::Name'".

IPC::Run allows you run and interact with child processes using files, pipes, and pseudo-ttys. Both system()-style and scripted usages are supported and may be mixed. Likewise, functional and OO API styles are both supported and may be mixed.

Safe::Hole can execute outside defined subroutines in the original main compartment from the Safe compartment.

Mail::Sendmail is a pure perl module that provides a simple means to send email from a perl script. The module only requires Perl5 and a network connection.

Writing exporters is a pain. Some use Exporter, some use Sub::Exporter, some use Moose::Exporter, some use Exporter::Declare ... and some things are pragmas. Exporting on someone else's behalf is harder. The exporters don't provide a consistent API for this, and pragmas need to have their import method called directly, since they effect the current unit of compilation. Import::Into provides global methods to make this painless.

Perl is a general-purpose programming language originally developed for text manipulation and now used for a wide range of tasks including system administration, web development, network programming, GUI development, and more.

Dates are complex enough without times and timezones. This module may be used to create simple date objects. It handles validation, interval arithmetic, and day-of-week calculation. It does not deal with hours, minutes, seconds, and time zones.

This package implements usleep, ualarm, and gettimeofday for Perl, as well as wrappers to implement time, sleep, and alarm that know about non-integral seconds.

MailTools contains the following modules:

Mail::Address

Parse email address from a header line.

Mail::Cap

Interpret mailcap files: mappings of file-types to applications as used by many command-line email programs.

Mail::Field

Simplifies access to (some) email header fields. Used by Mail::Header.

Mail::Filter

Process Mail::Internet messages.

Mail::Header

Collection of Mail::Field objects, representing the header of a Mail::Internet object.

Mail::Internet

Represents a single email message, with header and body.

Mail::Mailer

Send Mail::Internet emails via direct smtp or local MTA's.

Mail::Send

Build a Mail::Internet object, and then send it out using Mail::Mailer.

Mail::Util

"Smart functions" you should not depend on.

This module reads a file backwards line by line. It is simple to use, memory efficient and fast. It supports both an object and a tied handle interface.

It is intended for processing log and other similar text files which typically have their newest entries appended to them. By default files are assumed to be plain text and have a line ending appropriate to the OS. But you can set the input record separator string on a per file basis.

Strictures turns on strict and make all warnings fatal when run from within a source-controlled directory.

This is pragma to change Perl 5's standard method resolution order from depth-first left-to-right (a.k.a - pre-order) to the more sophisticated C3 method resolution order.

File::Temp can be used to create and open temporary files in a safe way.

YAML::Syck provides a Perl interface to the libsyck data serialization library. It exports the Dump and Load functions for converting Perl data structures to YAML strings, and the other way around.

Devel::Cycle This is a tool for finding circular references in objects and other types of references. Because of Perl's reference-count based memory management, circular references will cause memory leaks.

The namespace::autoclean pragma will remove all imported symbols at the end of the current package's compile cycle. Functions called in the package itself will still be bound by their name, but they won't show up as methods on your class or instances. It is very similar to namespace::clean, except it will clean all imported functions, no matter if you imported them before or after you used the pragma. It will also not touch anything that looks like a method.

Encode module provides the interface between Perl strings and the rest of the system. Perl strings are sequences of characters.

This module acts as a layer between Exporter and modules which consume exports. It is feature-compatible with Exporter, plus some much needed extras. You can use this to import symbols from any exporter that follows Exporters specification. The exporter modules themselves do not need to use or inherit from the Exporter module, they just need to set @EXPORT and/or other variables.

BinHex is a format for transporting files safely through electronic mail, as short-lined, 7-bit, semi-compressed data streams. This module provides a means of converting those data streams back into into binary data.

A String::Util module of small, handy functions for processing strings in various ways.

List::MoreUtils provides some trivial but commonly needed functionality on lists which is not going to go into List::Util.

This module understands the formats used by PostgreSQL for its DATE, TIME, TIMESTAMP, and INTERVAL data types. It can be used to parse these formats in order to create DateTime or DateTime::Duration objects, and it can take a DateTime or DateTime::Duration object and produce a string representing it in a format accepted by PostgreSQL.

This module allows libraries to have a dependency to a small module instead of the full Log-Report distribution. The full power of Log::Report is only released when the main program uses that module. In that case, the module using the Optional will also use the full Log::Report, otherwise the dressed-down Log::Report::Minimal version.
