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

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".

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.

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.)
