should recognise funcs already annotated with py3 PEP484 annotations #56
Description
if you run waterloo on your files, then run com2ann to convert to py3 PEP484 annotations, then re-run waterloo on them it will give some warnings about incomplete annotations
because waterloo only checks for # type: ... type comments to determine if func was already annotated
it should check for pre-existing p3 annotations too
