I've been lightly scanning and following the PEP 484 discussion, and one 
point I don't think I've seen mentioned is how you might hint a function 
that accepts different types, eg:

def adder(a,b): return a+b

This is one of the pythonic idioms that help with polymorphic functions. 
  Is there a proposal for providing hinting for these?

Thanks,
