Python 3.6 makes it sound like maps aren't iterable:
>>> map(str, *map(int, [[]]))
Traceback (most recent call last):
File "<pyshell#0>", line 1, in <module>
map(str, *map(int, [[]]))
TypeError: type object argument after * must be an iterable, not map
More, including a likely explanation, in my question and its answer here:

Apparently the TypeError from int([]) gets mistaken for a TypeError indicating non-iterability of the map object.

Thanks for the report. Retitling because this has nothing to do with map:
>>> def foo(*args):
... raise TypeError('fake')
... yield 1
...
>>> foo(1, *foo())
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: foo() argument after * must be an iterable, not generator
>>> foo(*foo())
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 2, in foo
TypeError: fake
