Re^3: A dispatch table to match named params of a sub

Since all your other subroutines take a single argument, you could also pass in an arrayref (as you currently do) and expand it into a hash inside the subroutine, *or* pass in a hashref and use it directly:

$ cat sploot2.pl
#!/usr/bin/env perl
use strict;
use warnings;
use Data::Dumper;
use Test::More;

my %sub = (
    t01=>{ name=>\&mine, args=>[qw/one first two second/] },
    t02=>{ name=>\&mine2, args=>{qw/one first two second/} },
);

for my $T (keys %sub) {
    $sub{$T}->{name}->($sub{$T}{args});
}
done_testing;

sub mine {
    # named arguments example
    my %args = @{$_[0]};

    ok( $args{one} eq 'first', 'arg one' );
    ok( $args{two} eq 'second', 'arg two' );
}

sub mine2 {
    # named arguments example
    my $args = shift;

    ok( $args->{one} eq 'first', 'arg one (b)' );
    ok( $args->{two} eq 'second', 'arg two (b)' );
}

$ perl sploot2.pl
ok 1 - arg one (b)
ok 2 - arg two (b)
ok 3 - arg one
ok 4 - arg two
1..4
