The substitute of writing `isinstance(x, collections.Callable)` is not good, 1) because it's wordier 2) because collections is really not an intuitive place where to look for a Callable ABC.
I thnk it should be in the abc module, along with WeakSet
The funny thing is that your rationale for not adding Picklable (just try and catch exception) is essentially the rationale for removing callable() ;-).
Well, I have never needed to know in advance whether an object was picklable or not, while knowing whether it's callable has come often. Regards Antoine.
