[issue31071] *args unpacking can mask TypeErrors

[R. David Murray]

R. David Murray added the comment:

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 "", line 1, in 
TypeError: foo() argument after * must be an iterable, not generator
>>> foo(*foo())
Traceback (most recent call last):
  File "", line 1, in 
  File "", line 2, in foo
TypeError: fake
