[Jeong-Min Lee]

New submission from Jeong-Min Lee <falsetru at gmail.com>:

Expected "TypeError: cannot concatenate 'str' and 'int' objects" exception raised, but got following result.


>>> def g():
...     '1' + 0
...     yield 1, 2
...     yield 3, 4
...
>>> zip(*g())
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: zip() argument after * must be a sequence, not generator
>>> (lambda xs: 0)(*g())
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: <lambda>() argument after * must be a sequence, not generator
>>> list(*g())
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: type object argument after * must be a sequence, not generator
>>> list(g())
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 2, in g
TypeError: cannot concatenate 'str' and 'int' objects
