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.

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.
