NAME

       Exporter::Tiny::Manual::Etc - odds and ends

DESCRIPTION

   Utility Functions
       Exporter::Tiny is itself an exporter!

       These functions are really for internal use, but can be exported if you need them:

       "mkopt(\@array)"
           Similar to "mkopt" from Data::OptList. It doesn't support all the fancy options that
           Data::OptList does ("moniker", "require_unique", "must_be" and "name_test") but runs
           about 50% faster.

       "mkopt_hash(\@array)"
           Similar to "mkopt_hash" from Data::OptList. See also "mkopt".

   History
       Type::Library had a bunch of custom exporting code which poked coderefs into its caller's
       stash. It needed this to be something more powerful than most exporters so that it could
       switch between exporting Moose, Mouse and Moo-compatible objects on request. Sub::Exporter
       would have been capable, but had too many dependencies for the Type::Tiny project.

       Meanwhile Type::Utils, Types::TypeTiny and Test::TypeTiny each used the venerable
       Exporter.pm. However, this meant they were unable to use the features like
       Sub::Exporter-style function renaming which I'd built into Type::Library:

          ## import "Str" but rename it to "String".
          use Types::Standard "Str" => { -as => "String" };

       And so I decided to factor out code that could be shared by all Type-Tiny's exporters into
       a single place: Exporter::TypeTiny.

       As of version 0.026, Exporter::TypeTiny was also made available as Exporter::Tiny,
       distributed independently on CPAN. CHOCOLATEBOY had convinced me that it was mature enough
       to live a life of its own.

       As of version 0.030, Type-Tiny depends on Exporter::Tiny and Exporter::TypeTiny is being
       phased out.

   Obligatory Exporter Comparison
       Exporting is unlikely to be your application's performance bottleneck, but nonetheless
       here are some comparisons.

       Comparative sizes according to Devel::SizeMe:

          Exporter                     217.1Kb
          Sub::Exporter::Progressive   263.2Kb
          Exporter::Tiny               267.7Kb
          Exporter + Exporter::Heavy   281.5Kb
          Exporter::Renaming           406.2Kb
          Sub::Exporter                701.0Kb

       Performance exporting a single sub:

                     Rate     SubExp    ExpTiny SubExpProg      ExpPM
       SubExp      2489/s         --       -56%       -85%       -88%
       ExpTiny     5635/s       126%         --       -67%       -72%
       SubExpProg 16905/s       579%       200%         --       -16%
       ExpPM      20097/s       707%       257%        19%         --

       (Exporter::Renaming globally changes the behaviour of Exporter.pm, so could not be
       included in the same benchmarks.)

       (Non-Core) Dependencies:
