The Error package provides two interfaces. Firstly Error provides a procedural interface to exception handling. Secondly Error is a base class for errors/exceptions that can either be thrown, for subsequent catch, or can simply be recorded.

Carp::Assert is intended for a purpose like the ANSI C library assert.h.

Getopt::Tabular is a Perl 5 module for table-driven argument parsing, vaguely inspired by John Ousterhout's Tk_ParseArgv.

This module adds the ability to quickly create new types of tie objects without creating a complete class. It does so in such a way as to try and make the programmers life easier when it comes to single-use ties that I find myself wanting to use from time-to-time.

The Tie::Simple package is actually a front-end to other classes which really do all the work once tied, but this package does the dwimming to automatically figure out what you're trying to do.

This package is a companion module to DateTime.pm. It implements the Julian calendar. It supports everything that DateTime.pm supports and more: about one day per century more, to be precise.

This module provides a Log::Any adapter to send log messages to screen, with colors and some other features.

Ref::Util introduces several functions to help identify references in a smarter (and usually faster) way. The difference with conventional approach:

• No comparison against a string constant

• Supports blessed variables

• Supports tied variables and magic

• Ignores overloading

• Ignores subtle types

• Usually faster

Class::Inspector allows you to get information about a loaded class.

Similar to List::MoreUtils, Hash::MoreUtils contains trivial but commonly-used functionality for hashes. The primary focus for the moment is providing a common API - speeding up by XS is far away at the moment.

Data::OptList provides a simple syntax for name/value option pairs.

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.

File::Remove::remove removes files and directories. It acts like /bin/rm, for the most part. Although unlink can be given a list of files, it will not remove directories; this module remedies that. It also accepts wildcards, * and ?, as arguments for file names.

This module provides a file handle that hides the beginning of a file, by modifying the seek() and tell() calls.

Alien::SDL can be used to detect and get configuration settings from an installed SDL and related libraries. Based on your platform it offers the possibility to download and install prebuilt binaries or to build SDL & co.: from source codes.

Set::Object provides efficient sets, unordered collections of Perl objects without duplicates for scalars and references.

This module provides tools to deal with International Standard Music Numbers.

IPC::Cmd allows for the searching and execution of any binary on your system. It adheres to verbosity settings and is able to run interactively. It also has an option to capture output/error buffers.

This module provides Path::Tiny types for Moose, Moo, etc. It handles two important types of coercion: coercing objects with overloaded stringification, and coercing to absolute paths. It also can check to ensure that files or directories exist.

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

This module provides syntactical support for try/catch control flows.

This module provides a clone() method which makes recursive copies of nested hash, array, scalar and reference types, including tied variables and objects.

Internationalized Domain Names (IDNs) use characters drawn from a large repertoire (Unicode), but IDNA allows the non-ASCII characters to be represented using only the ASCII characters already allowed in so-called host names today (letter-digit-hyphen, /[A-Z0-9-]/i).

Use this module if you just want to convert domain names (or email addresses), using whatever IDNA standard is the best choice at the moment.

Test::Count is a set of perl modules for keeping track of the number of tests in a test file. It includes the ability to use mathematical expressions and variables when computing the count.

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