Like Tcl's uplevel() function, but not quite so dangerous. The idea is just to fool caller(). All the really naughty bits of Tcl's uplevel() are avoided.

Number::Compare compiles a simple comparison to an anonymous subroutine, which you can call with a value to be tested against.

Calling Perl's in-built system function is easy, determining if it was successful is hard. Let's face it, $? isn't the nicest variable in the world to play with, and even if you do check it, producing a well-formatted error string takes a lot of work.

IPC::System::Simple takes the hard work out of calling external commands.

This module provides a basic way to discover if a piece of perl code is allocating perl data and not releasing them again.

This module attempts to recover from people calling UNIVERSAL::isa as a function.

This module provides a list of known mime-types, combined from various sources. For instance, it contains all IANA types and the knowledge of Apache.

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.

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.

Crypt::UnixCrypt_XS implements the DES-based Unix crypt function. For those who need to construct non-standard variants of crypt, the various building blocks used in crypt are also supplied separately.

This module implements a subset of the YAML specification for use in reading and writing CPAN metadata files like META.yml and MYMETA.yml.

App::Nopaste provides easy access to any pastebin.

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.

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.

This policy checks for perlsecret operators in your code and warns you about them. You can override the secrets that are allowed or disallowed using the parameters allow_secrets and disallow_secrets. The default is to simply disallow everything.

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

This package provides Digest::SHA1, an implementation of the NIST SHA-1 message digest algorithm for use by Perl programs.

The Lingua::EN::Sentence module contains the function get_sentences, which splits text into its constituent sentences, based on a regular expression and a list of abbreviations (built in and given).

This module first checks to see if either Cpanel::JSON::XS or JSON::XS is already loaded, in which case it uses that module. Otherwise it tries to load Cpanel::JSON::XS, then JSON::XS, then JSON::PP in order, and either uses the first module it finds or throws an error.

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

This module is meant as a debugging aid. It can be used to make a script complain loudly with stack backtraces when warn()-ing or die()ing.

This module provides some XS functions to assist in writing parsers for sub-like syntax, primarily for authors of keyword plugins using the PL_keyword_plugin hook mechanism.

Authen-Passphrase is the base class for a system of objects that encapsulate passphrases. An object of this type is a passphrase recogniser; its job is to recognise whether an offered passphrase is the right one. For security such passphrase recognisers usually do not themselves know the passphrase they are looking for; they can merely recognise it when they see it. There are many schemes in use to achieve this effect and the intent of this class is to provide a consistent interface to them all. In addition to the base class, this module also contains implementations of several specific passphrase schemes.

Assigns a new name to referenced sub. If package specification is omitted in the name, then the current package is used. The return value is the sub.

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