Module::Refresh provides ways to refresh %INC files when updated on disk.

MooseX::Types::LoadableClass provides a ClassName type constraint with coercion to load the class.

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

Circos is a program for the generation of publication-quality, circularly composited renditions of genomic data and related annotations.

This module provides some XS functions to assist in writing syntax modules that provide new perl-visible syntax, primarily for authors of keyword plugins using the PL_keyword_plugin hook mechanism.

Hash::Merge merges two arbitrarily deep hashes into a single hash. That is, at any level, it will add non-conflicting key-value pairs from one hash to the other, and follows a set of specific rules when there are key value conflicts. The hash is followed recursively, so that deeply nested hashes that are at the same level will be merged when the parent hashes are merged.

This package provides an ASCII mapping for the eucJP encoding.

PAR::Dist is a toolkit to create and manipulate PAR distributions.

The first priority of Set::Scalar is to be a convenient interface to sets (as in: unordered collections of Perl scalars). While not designed to be slow or big, neither has it been designed to be fast or compact.

This module provides three utility subroutines that make it easier to develop interactive applications: is_interactive(), interactive(), and busy().

This module will inject base classes to your module using the Class::C3 method resolution order.

While Mouse attributes provide a way to name your accessors, readers, writers, clearers and predicates, MouseX::NativeTraits provides commonly used attribute helper methods for more specific types of data.

RFCs 2822 and 822 specify date formats to be used by email. This module parses and emits such dates.

B::Keywords supplies several arrays of exportable keywords: @Scalars, @Arrays, @Hashes, @Filehandles, @Symbols, @Functions, @Barewords, @TieIOMethods, @UNIVERSALMethods and @ExporterSymbols.

Time::Duration::Parse is a module to parse human readable duration strings like "2 minutes" and "3 seconds" to seconds.

The Regexp::Grammars module adds a small number of new regex constructs that can be used within Perl 5.10 patterns to implement complete recursive-descent parsing. It allows you to go beyond matching complex, nested and recursive structures, and allows you to parse and extract hierarchical data from it.

Devel::CheckLib is a Perl module that checks whether a particular C library and its headers are available. You can also check for the presence of particular functions in a library, or even that those functions return particular results.

Config::Grammar is a module to parse configuration files. The configuration may consist of multiple-level sections with assignments and tabular data.

The Text::Balanced module can be used to extract delimited text sequences from strings.

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.

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

This module lets you attempt to measure, from your operating system's perspective, how much memory a process is using at any given time.

Role::Tiny is a minimalist role composition tool.

DateTime::Format::Builder creates DateTime parsers. Many string formats of dates and times are simple and just require a basic regular expression to extract the relevant information. Builder provides a simple way to do this without writing reams of structural code.
