Thanks for the answer. I will go with Method::Signatures::Simple in the end. (I would have liked signatures for functions.) Now I just need to see if someone has updated CPerl mode in Emacs (edit: to recognize the 'method' instead of just 'sub').

Re Moo -- I am writing a hobby hack; a bit experimental sounds OK. :-) Also, if there are problems -- as far as I can tell, it should be quite easy to switch to Moose/Mouse.
