'vars' has been considered deprecated for years now. 'our' should be used unless your using an old version of perl or legacy perl programs.

corelist

CORELIST(1)						 Perl Programmers Reference Guide					       CORELIST(1)

NAME

       corelist - a commandline frontend to Module::CoreList

DESCRIPTION

       See Module::CoreList for one.

SYNOPSIS

	   corelist -v
	   corelist [-a|-d] <ModuleName> | /<ModuleRegex>/ [<ModuleVersion>] ...

	   corelist [-r <PerlVersion>] ...
	   corelist --diff PerlVersion PerlVersion

OPTIONS

       -a  lists all versions of the given module (or the matching modules, in case you used a module regexp) in the perls Module::CoreList knows
	   about.

	       corelist -a Unicode

       -d  finds the first perl version where a module has been released by date, and not by version number (as is the default).

       --diff
	   Given two versions of perl, this prints a human-readable table of all module changes between the two.  The output format may change in
	   the future, and is meant for humans, not programs.  For programs, use the Module::CoreList API.

       -? or -help
	   help! help! help! to see more help, try --man.

       -man
	   all of the help

       -v  lists all of the perl release versions we got the CoreList for.

	   If you pass a version argument (value of $], like 5.00503 or 5.008008), you get a list of all the modules and their respective
	   versions.  (If you have the "version" module, you can also use new-style version numbers, like 5.8.8.)

	   In module filtering context, it can be used as Perl version filter.

       -r  lists all of the perl releases and when they were released

	   If you pass a perl version you get the release date for that version only.

       As a special case, if you specify the module name "Unicode", you'll get the version number of the Unicode Character Database bundled with
       the requested perl versions.

EXAMPLES

	   $ corelist File::Spec

	   File::Spec was first released with perl 5.005

	   $ corelist File::Spec 0.83

	   File::Spec 0.83 was released with perl 5.007003

	   $ corelist File::Spec 0.89

	   File::Spec 0.89 was not in CORE (or so I think)

	   $ corelist File::Spec::Aliens

	   File::Spec::Aliens  was not in CORE (or so I think)

	   $ corelist /IPC::Open/

	   IPC::Open2 was first released with perl 5

	   IPC::Open3 was first released with perl 5

	   $ corelist /MANIFEST/i

	   ExtUtils::Manifest was first released with perl 5.001

	   $ corelist /Template/

	   /Template/  has no match in CORE (or so I think)

	   $ corelist -v 5.8.8 B

	   B			    1.09_01

	   $ corelist -v 5.8.8 /^B::/

	   B::Asmdata		    1.01
	   B::Assembler 	    0.07
	   B::Bblock		    1.02_01
	   B::Bytecode		    1.01_01
	   B::C 		    1.04_01
	   B::CC		    1.00_01
	   B::Concise		    0.66
	   B::Debug		    1.02_01
	   B::Deparse		    0.71
	   B::Disassembler	    1.05
	   B::Lint		    1.03
	   B::O 		    1.00
	   B::Showlex		    1.02
	   B::Stackobj		    1.00
	   B::Stash		    1.00
	   B::Terse		    1.03_01
	   B::Xref		    1.01
