I actually avoid map.

map works as intended; there's nothing particularly wrong with it. In
fact I believe it's pretty important in lisp, but it's a rather
glaring example of TMTOWTDI in Python.

BTW, I believe in Python 2.x map is like a list comprehension, but in
3.x map is like a generator expression.
