[issue17584] collections.Iterator __subclasshook__ does not check if next() is callable

Byron Ruth added the comment:

Thank you for the education. I didn't think about duck-typing extending to the level of whether or not something is callable.. then again the property _could_ return a callable and it would be transparent to the caller.
