That shouldn't be a problem: Just put all arguments in your dispatch has in arrayrefs, and when they're unwrapped, they'll be simple positional parameters. Having one is just fine. It's probably the most general form, as you can also pass an array of arguments, too, so you get it all: single arguments, multiple arguments, arrays, hashes and named arguments (hashes!).

$ cat #!/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=>\&yours, args=>[ 'foo' ] }, t03=>{ name=>\&ours, args=>[qw/The quick red fox/] }, ); for my $T (keys %sub) { $sub{$T}->{name}->(@{$sub{$T}{args}}); } done_testing; sub mine { # named arguments example my %args = @_; ok( $args{one} eq 'first', 'arg one' ); ok( $args{two} eq 'second', 'arg two' ); } sub yours { # single argument example my $message = shift; ok( $message eq 'foo', 'A single argument' ); } sub ours { # array example my @args = @_; ok( "The quick red fox" eq join(" ", @args), 'Argument array' ); } Roboticus@Waubli ~ $ perl ok 1 - Argument array ok 2 - A single argument ok 3 - arg one ok 4 - arg two 1..4

Update: Added array example & text


When your only tool is a hammer, all problems look like your thumb.
