Method::Signatures::Simple - Basic method declarations with signatures, without source filters

Version 0.03

use Method::Signatures::Simple;
method foo { $self->bar }
# with signature
method foo($bar, %opts) {
$self->bar(reverse $bar) if $opts{rev};
}
# attributes
method foo : lvalue { $self->{foo} }
# change invocant name
method foo ($class: $bar) { $class->bar($bar) }

This module provides a basic method keyword with simple signatures. It's intentionally simple, and is supposed to be a stepping stone for its bigger brothers MooseX::Method::Signatures and Method::Signatures. It only has a small benefit over regular subs, so if you want more features, look at those modules. But if you're looking for a small amount of syntactic sugar, this might just be enough.

The method keyword automatically injects the annoying my $self = shift; for you. You can rename the invocant with the first argument, followed by a colon:
method ($this:) {}
method ($this: $that) {}
The signature ($sig) is transformed into "my ($sig) = \@_;". That way, we mimic perl's usual argument handling.
method foo ($bar, $baz, %opts) {
# becomes
sub foo {
my $self = shift;
my ($bar, $baz, %opts) = @_;

For writing Devel::Declare and providing the core concepts.
For writing Method::Signatures and publishing about it. This is what got my attention.
For helping me abstracting the Devel::Declare bits and suggesting improvements.

Devel::Declare, Method::Signatures, MooseX::Method::Signatures.
