So write

class.method(name:str, count:int)->return_type # 3.x

if you really prefer.

In spite of you disparagement of 'pythonistas', it seems that the head 
pythonista *did* admit that some people, at least, would prefer such 
annotations.

3.0 also added abstract base classes so one can better specify object 
classes without losing duck-typing.

import numbers
class.method(name:str, count:numbers.Integral)->return_type

Now one is documenting that count should be an integral value that acts 
like an integer even if it is not an int per se. Of course, this is too 
broad as it allows (presumably invalid) negative values.
