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

PadWalker is a module which allows you to inspect (and even change) lexical variables in any subroutine which called you. It will only show those variables which are in scope at the point of the call. PadWalker is particularly useful for debugging.

The Term::Animation Perl module provides a framework to produce sprite animations using ASCII art. Each ASCII 'sprite' is given one or more frames, and placed into the animation as an 'animation entity'. An animation entity can have a callback routine that controls the position and frame of the entity. The module can also do collision detection between entities.

This module defines a single regex that will match syntactically valid Perl documents, or valid components (such as statements, expressions, blocks, strings, etc.)

This module allows you to specify conflicting versions of modules separately and deal with them after the module is done installing.

List::Compare provides a module to perform comparative operations on two or more lists. Provided operations include intersections, unions, unique elements, complements and many more.

This module fills a gap in Moose by adding method parameter validation to Moose.

Exporter::Lite is an alternative to Exporter, intended to provide a lightweight subset of the most commonly-used functionality. It supports import(), @EXPORT and @EXPORT_OK and not a whole lot else.

Type::Tiny is a small class for writing type constraints, inspired by Moose's type constraint API. It has only one non-core dependency (and even that is simply a module that was previously distributed as part of Type::Tiny but has since been spun off), and can be used with Moose, Mouse and Moo (or none of the above).

Magic is Perl's way of enhancing variables. This mechanism lets the user add extra data to any variable and hook syntactical operations (such as access, assignment or destruction) that can be applied to it. With this module, you can add your own magic to any variable without having to write a single line of XS.

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

This module tries to make install path resolution as easy as possible.

SVG is a Perl module which generates a nested data structure containing the DOM representation of an SVG (Scalable Vector Graphics) image. Using SVG, you can generate SVG objects, embed other SVG instances into it, access the DOM object, create and access Javascript, and generate SMIL animation content.

The functions exported by this module allow you to open URLs in the user's browser. A set of known commands per OS-name is tested for presence, and the first one found is executed. With an optional parameter, all known commands are checked.

File locking in Perl is usually done using the flock function. Unfortunately, this only allows locks on whole files and is often implemented in terms of the flock(2) system function which has some shortcomings (especially concerning locks on remotely mounted file systems) and slightly different behaviour than fcntl(2).

A Sub::Override module that makes it easy to override subroutines. Particularly useful for mocking in tests.

This module is a data dumper optimized for logging of arbitrary parameters.

The Digest::CRC module calculates CRC sums of all sorts. It contains wrapper functions with the correct parameters for CRC-CCITT, CRC-16 and CRC-32.

This module provides a simple syntax for creating object classes.

This way of associating structs with Perl space objects is designed to supersede Perl's builtin T_PTROBJ with something that is extensible (structs can be associated with any data type) and opaque (the C pointer is neither visible nor modifiable from Perl space).

This module exports methods useful for factory classes.

This is a Perl package designed to generate browsable HTML documentation from the POD (Plain Old Documentation) embedded in Perl source code.

File::Zglob provides a traditional Unix glob functionality; it returns a list of file names that match the given pattern. For instance, it supports the **/*.pm form.

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.
