NAME
    Bencher::Scenario::BagComparison - Benchmark bag comparison

VERSION
    This document describes version 0.005 of
    Bencher::Scenario::BagComparison (from Perl distribution
    Bencher-Scenario-BagComparison), released on 2021-07-31.

SYNOPSIS
    To run benchmark with default option:

     % bencher -m BagComparison

    To run module startup overhead benchmark:

     % bencher --module-startup -m BagComparison

    For more options (dump scenario, list/include/exclude/add participants,
    list/include/exclude/add datasets, etc), see bencher or run "bencher
    --help".

DESCRIPTION
    TODO: find another bag comparison module.

    TODO: compare complex elements.

    TODO: compare with Data::Compare + sorting.

    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
    Bencher and bencher (CLI) for more details.

    sample benchmark.

BENCHMARK PARTICIPANTS
    *   Test::Deep (perl_code)

        Code template:

         state $bag = Test::Deep::bag(@{<bag>}); Test::Deep::eq_deeply(<array>, $bag)
