=head1 DESCRIPTION
Packaging a benchmark script as a Bencher scenario makes it convenient to include/exclude/add participants/datasets (either via CLI or Perl code), send the result to a central repository, among others . See L<Bencher> and L<bencher> (CLI) for more de...
=head1 BENCHMARK NOTES
The Type::Tiny, Data::Sah, Perinci::Sub::ValidateArgs participants (except
C<none>, obviously) all should be in the same order of magnitude because both
L<Data::Sah> and L<Type::Tiny> work by generating Perl code validator and then
compiling (C<eval()>) them then execute the compiled result. The differences are
in the details: how the generated Perl code is structured, what the code for the
type checks are (e.g. checking for number can be done with a regex or
L<Scalar::Util>'s C<looks_like_number()> or L<Scalar::Util::Numeric>, and so
on).
Perinci::Sub::Wrapper (PSW) and Dist::Zilla::Plugin::Rinci::Wrap is slower
because it does more.
