I was referring to two of the most popular idioms to dynamically create a dict.
d = {}
for x in a:
d[k(x)] = v(x)
d = {k(x): v(x) for x in a}
For now these methods are consistent.
I agree that the use of the side effects here is not a sensible idea, but when
such effects occur by accident, it will cause a surprise.
