Too late. :-)

I was not around here, and although I looked for, I didn't find this on the web:

What was the reasoning for removing "callable" in the first place?

It didn't always do exactly the right thing (but was usually "good enough") and was thought easy to replace with a more accurate alternative (isinstance(foo, abc.Callable) I *think*) which proved annoying in pactise.

All the best,
