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.
