( #3333=superdoc: print w/replies, xml ) Need Help??
My issue with the way it works now, is that I can explicitly call a method by using it's full name (Class::Method), thereby bypassing the implicit passing of the first argument. I'd feel safe if there was an easy way to tell my method to do a solid type-check on the first argument, to ensure it's an object or class-name it can work with.

Right now I do this with the same lines of code again and again, and I'm assuming I'm not the only one doing this kind of check. All the modifiers would add is an implicit check for a valid first argument, possibly pre-assigning it to a 'magic' variable, and leaving the actual arguments in @_...

But as Aristotle pointed out, something quite similar can be done by using Attribute::Handlers. I would define an attribute handler for the 'Method', 'Class' and 'Instance' attributes...
