    Usage:

     gen_bencher_scenario(%args) -> [status, msg, payload, meta]

    Generate/extract Bencher scenario from information in an
    Acme::CPANModules::* list.

    An Acme::CPANModules::* module can contain benchmark information, for
    example in Acme::CPANModules::TextTable, each entry has the following
    property:

       entries => [
           ...
           {
               module => 'Text::ANSITable',
               ...
               bench_code => sub {
                   my ($table) = @_;
                   my $t = Text::ANSITable->new(
                       use_utf8 => 0,
                       use_box_chars => 0,
                       use_color => 0,
                       columns => $table->[0],
                       border_style => 'Default::single_ascii',
                   );
                   $t->add_row($table->[$_]) for 1..@$table-1;
                   $t->draw;
               },
 
               # per-function participant
               functions => {
                   'func1' => {
                       bench_code_template => 'Text::ANSITable::func1([])',
                   },
                   ...
               },

    The list also contains information about the benchmark datasets:

     bench_datasets => [
         {name=>'tiny (1x1)'    , argv => [_make_table( 1, 1)],},
         {name=>'small (3x5)'   , argv => [_make_table( 3, 5)],},
         {name=>'wide (30x5)'   , argv => [_make_table(30, 5)],},
         {name=>'long (3x300)'  , argv => [_make_table( 3, 300)],},
         {name=>'large (30x300)', argv => [_make_table(30, 300)],},
     ],

    This routine extract those information and return a Bencher scenario
    structure.

    This function is not exported by default, but exportable.

    Arguments ('*' denotes required arguments):

    *   cpanmodule* => *perl::modname*

        Name of Acme::CPANModules::* module, without the prefix.

    Returns an enveloped result (an array).

    First element (status) is an integer containing HTTP status code (200
    means OK, 4xx caller error, 5xx function error). Second element (msg) is
    a string containing error message, or 'OK' if status is 200. Third
    element (payload) is optional, the actual result. Fourth element (meta)
    is called result metadata and is optional, a hash that contains extra
    information.

    Return value: (any)
