I want to do what the author of the original post in this thread asked for:
automatically wrap all my methods with custom code. I have a module
(MooseX::Params) that performs argument processing for subs via attributes,
e.g.:
sub foo :Args(bar, baz) { ... }
The wrapping is triggered by the application of a subroutine attribute (e.g.
'Args'). However, I would prefer an interface where the signature is specified
in the prototype slot of the sub:
sub foo (bar, baz) { ... }
As it happens, I can do that with the warnings::illegalproto pragma, but in
that case there is no event to fire the wrapping code. A hook that gets
triggered after the compilation of the sub will solve this (this is the
approach the signatures pragma uses).
This is not strictly a Moose question, it's just that the discussion started
here.
Cheers,
