NAME

       perl5i::latest - Use the latest version of perl5i

SYNOPSIS

	   use perl5i::latest;

DESCRIPTION

       Because perl5i is designed to break compatibility, you must declare which major version you're writing your code with to preserve
       compatibility.  If you want to be more daring, you can "use perl5i::latest" and it will load the newest major version of perl5i you have
       installed.

       perl5i WILL BREAK COMPATIBILITY, believe it.  This is mostly useful for one-off scripts and one-liners and digital thrill seekers.

NAME

       true - automatically return a true value when a file is required

SYNOPSIS

	 package Contemporary::Perl;

	 use strict;
	 use warnings;
	 use true;

	 sub import {
	     strict->import();
	     warnings->import();
	     true->import();
	 }

DESCRIPTION

       Perl's "require" builtin (and its "use" wrapper) requires the files it loads to return a true value.  This is usually accomplished by
       placing a single

	   1;

       statement at the end of included scripts or modules. It's not onerous to add but it's a speed bump on the Perl novice's road to
       enlightenment. In addition, it appears to be a non-sequitur to the uninitiated, leading some to attempt to mitigate its appearance with a
       comment:

	   1; # keep require happy

       or:

	   1; # Do not remove this line

       or even:

	   1; # Must end with this, because Perl is bogus.

       This module packages this "return true" behaviour so that it need not be written explicitly.  It can be used directly, but it is intended
       to be invoked from the "import" method of a Modern::Perl-style module that enables modern Perl features and conveniences and cleans up
       legacy Perl warts.

   METHODS
       "true" is file-scoped rather than lexically-scoped. Importing it anywhere in a file (e.g. at the top-level or in a nested scope) causes
       that file to return true, and unimporting it anywhere in a file restores the default behaviour. Redundant imports/unimports are ignored.

       import

       Enable the "automatically return true" behaviour for the currently-compiling file. This should typically be invoked from the "import"
       method of a module that loads "true". Code that uses this module solely on behalf of its callers can load "true" without importing it e.g.

	   use true (); # don't import

	   sub import {
	       true->import();
	   }

	   1;

       But there's nothing stopping a wrapper module also importing "true" to obviate its own need to explicitly return a true value:

	   use true; # both load and import it

	   sub import {
	       true->import();
	   }

	   # no need to return true

       unimport

       Disable the "automatically return true" behaviour for the currently-compiling file.

   EXPORT
       None by default.

NOTES

       Because some versions of YAML::XS may interpret the key of "true" as a boolean, you may have trouble declaring a dependency on true.pm.
       You can work around this by declaring a dependency on the package true::VERSION, which has the same version as true.pm.
