[New-bugs-announce] [issue32046] 2to3 fix for operator.isCallable()

[Serhiy Storchaka]

New submission from Serhiy Storchaka <storchaka+cpython at gmail.com>:

Currently 2to3 converts `operator.isCallable(obj)` to `hasattr(obj, '__call__')`. This looks cumbersome, and can be deceived by instance attribute __call__. The more correct way is to use `isinstance(obj, collections.abc.Callable)`. Starting from Python 3.2 it can use the callable() builtin.
