These functions are really for internal use, but can be exported if you need them: =over =item C<< mkopt(\@array) >> Similar to C<mkopt> from L<Data::OptList>. It doesn't support all the fancy options that Data::OptList does (C<moniker>, C<require_unique>, C<must_be> and C<name_test>) but runs about 50% faster. =item C<< mkopt_hash(\@array) >> Similar to C<mkopt_hash> from L<Data::OptList>. See also C<mkopt>. =back =head2 History L<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. L<Sub::Exporter> would have been capable, but had too many dependencies for the Type::Tiny project. Meanwhile L<Type::Utils>, L<Types::TypeTiny> and L<Test::TypeTiny> each used the venerable L<Exporter.pm|Exporter>. However, this meant they were unable to use the features like L<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 L<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. =head2 Obligatory Exporter Comparison Exporting is unlikely to be your application's performance bottleneck, but nonetheless here are some comparisons.
