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 doesn't need to 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.

   EXPORTS
       None by default.

NOTES

       Because the unquoted name "true" represents the boolean value "true" in YAML, the module
       name must be quoted when written as a dependency in META.yml. In cases where this can't
       easily be done, a dependency can be declared on the package true::VERSION, which has the
       same version as "true.pm".
