# Exporter::Tiny::Manual::Etc - phpMan

## 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.)
