I guess this is an area where PEP 318 should be fleshed out a bit. I don't see any reason it shouldn't be expanded to include semantics as well as syntax. That might require a title change, but I don't think the semantics should be left unspecified, nor do I think the syntax and semantics should reside in separate PEPs. I agree. FWIW, I think the list of things inside the square brackets should be simple identifiers, i.e. the names of callables that have been defined elsewhere. I'd prefer to keep them simple, meaning no lambdas or list comprehensions. But that's just me.

I'd would prefer allowing function calls as well. One of the reasons for using function wrappers is adding type information to functions (PyObjC and ctype), like so:

def myMethod_(self) [signature("i@:i")]:
    pass
