NAME

Sub::Multi::Tiny - Multisubs/multimethods (multiple dispatch) yet another way!

SYNOPSIS

{
    package main::my_multi;     # We're making main::my_multi()
    use Sub::Multi::Tiny qw($foo $bar);     # All possible params

    sub first :M($foo, $bar) { # sub's name will be ignored
        return "first";
    }

    sub second :M($foo) {
        return "second";
    }

}

# Back in package main, my_multi() is created just before the run phase.
say my_multi("a scalar", "and some more");  # -> "first"
say my_multi("just a scalar");              # -> "second"

Limitation: At present, dispatch is solely by arity, and only one candidate can have each arity. This limitation will be removed in the future.

DESCRIPTION

Sub::Multi::Tiny is a library for making multisubs, aka multimethods, aka multiple-dispatch subroutines.

TODO explain: if sub MakeDispatcher() exists in the package, it will be called to create the dispatcher.

RATIONALE / SEE ALSO

TODO explain why yet another module!

Logic

This one is fairly clean, but uses a source filter. I have not had much experience with source filters, so am reluctant.

Kavorka::Manual::MultiSubs (and Moops)
MooseX::MultiMethods

I am not ready to move to full Moose!

MooseX::Params

As above.

Sub::Multi
Sub::SmartMatch

This one looks very interesting, but I haven't used smartmatch enough to be fully comfortable with it.

SUPPORT
