I guess I can kinda see that analogy. But a loop is an assignment, and
this doesn't mean "flatten":
a, b, *c = 1, 2, 3, 4, 5, 6
Moreover, in a regular loop:
>>> for *x in [a, b, c]:
... print(x)
File "<ipython-input-13-a22866454ece>", line 1
for *x in [a, b, c]:
^
SyntaxError: starred assignment target must be in a list or tuple
Neither of my examples, I admit, are quite the same as the comprehension.
Nonetheless, I definitely don't think the proposed syntax is "the one
obvious way to do it."
