Allow str.replace's 'count' to be a keyword argument

[hugovk]

Feature or enhancement

Allow the count argument of str.replace to be a keyword to better describe its use.

Pitch

str.replace takes old and new strings as parameters, and an optional count parameter:

https://docs.python.org/3/library/stdtypes.html#str.replace

However, count cannot be a keyword argument:

>>> "aaa".replace("a", "b", 2)
'bba'
>>> "aaa".replace("a", "b", count=2)
TypeError: str.replace() takes no keyword arguments

It would be more explicit if the count parameter could also be a keyword, so there's no doubt about its meaning.
