Why don't you just use one of the signatures modules? E.g.,
#! /usr/bin/perl
use MooseX::Declare;
use Method::Signatures::Modifiers;
class Foo
{
method foo ($bar, $baz)
{
print $self->frobnabulate($bar, $baz);
}
}
Foo->new->foo(1, 2, 3);
produces:
In call to Foo::foo(), was given too many arguments, it expects 2 at
t.pl line 13.
If you don't like the MooseX::Declare stuff, it should work equally
well with just Method::Signatures. I'm pretty sure there's a place to
hook into MS or MSM somewhere post-compilation, but, if there isn't,
perhaps we could add it.
Maybe there's some reason this can't work that I'm not seeing, but it
seems to me like you're trying to solve a problem that's already been
solved pretty well, but in a roundabout way instead of using the known
solutions as a jumping off point. Hopefully this can trigger a
lightbulb in your head, but, if not, feel free to ignore me. :-)
