Replace for-append with generator

[Tadaboody]

New smell

Smelly code

li = list()
for x in other_iterable:
    # Body
    li += expr

Fixed code

def generate_li():
    # Body
    yield expr
li = list(generate_li())

Why is it smelly?

Not as smelly:tm: as other things, but in some cases it makes more sense, and more people should be aware of the possibility.
