I'm not going to argue the point. All I know is that code that worked in Py2 failed in
spectacularly obscure ways when I was making the FFF CLI run in Py3.
And rather than worry about the esoteric details about how and why they are different, I decided filter() & map() are simply broken and not to be used in code that needs to run on both Py2 and Py3.

From what I understand (which I admit is very shallow), they were the 'pythonic' solutions before list comprehension came along to avoid writing loops and were extremely common. In my ignorance, I copied them from older code which probably copied from even older code.
Okay, I may be arguing the point a bit after all...
