The package contains the ExtUtils::ParseXS module to convert Perl XS code into C code, the ExtUtils::Typemaps module to handle Perl/XS typemap files, and their submodules.

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

The Time::Warp module offers developers control over the measurement of time.

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

This module replaces the standard localtime and gmtime functions with implementations that return objects. It does so in a backwards-compatible manner, so that using these functions as documented will still work as expected.

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.

ExtUtils::Config is an abstraction around the %Config hash. By itself it is not a particularly interesting module by any measure, however it ties together a family of modern toolchain modules.

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

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

This module provides functions to encode and decode UTF-8 encoding form as specified by Unicode and ISO/IEC 10646:2011.

Guard implements so-called guards. A guard is something (usually an object) that "guards" a resource, ensuring that it is cleaned up when expected.

Specifically, this module supports two different types of guards: guard objects, which execute a given code block when destroyed, and scoped guards, which are tied to the scope exit.

XSLoader module defines a standard simplified interface to the dynamic linking mechanisms available on many platforms. Its primary purpose is to implement cheap automatic dynamic loading of Perl modules.

This Perl module allows you to split data into records by not only specifying what you wish to split the data on, but also by specifying an "unless" regular expression. If the text in question matches the "unless" regex, it will not be split there. This allows us to do things like split on newlines unless newlines are embedded in quotes.

The namespace::clean pragma will remove all previously declared or 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.

This package provides tools for sorting and comparing Unicode data.

This module provides functions for fast and correct file slurping and spewing. All functions are optionally exported.

Mozilla::CA provides a copy of Mozilla's bundle of Certificate Authority certificates in a form that can be consumed by modules and libraries based on OpenSSL.

This module is an alternative to String::Trim. Instead of a single trim function, this module provides several from which you can choose on, depending on your needs.

File::ShareDir::Install allows you to install read-only data files from a distribution. It is a companion module to File::ShareDir, which allows you to locate these files after installation.

This module provides an XS implementation for portions of Class::Load.

Date::Manip is a series of modules for common date/time operations, such as comparing two times, determining a date a given amount of time from another, or parsing international times.

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 library provides a set of Path::Tiny types and coercions for Specio. These types can be used with Moose, Moo, Params::ValidationCompiler, and other modules.

This module is optionally used by Type::Tiny to provide faster, C-based implementations of some type constraints. This package has only core dependencies, and does not depend on Type::Tiny, so other data validation frameworks might also consider using it.
