My 2c:
I don't remember ever seeing itertools.compress (although I've
occasionally browsed through itertools), and I've certainly never used
it. However, having worked out what it does, my first reaction was that
this would be a harmless and mildly convenient change. But might it not
lead to bugs if the second argument were accidentally omitted?
Best wishes

Hi!
I propose to enhance "itertools.compress" in such a way so if you don't provide selectors, then "data" itself is used as a selectors.
So "compress(a)" would be equivalent to "compress(a, a)"
For example:
from itertools import compress
[*compress([0, 1, 2, 3]))]
[1, 2, 3]
[*compress(["", "CFLAGS=-O3"])]
["CFLAGS=-O3"]
opts = compress([None, "", "-filove-python", "CFLAGS=-O3"])
" ".join(opts)
'-filove-python CFLAGS=-O3'
What do you think guys about this? Perhaps it was proposed by someone else?
Thanks!
