IronPython treats lists in for loop the same as tuples

[ironpythonbot]

Given the code:

x = {2:3}

for [[i], [j]] in x.items(): print(i, j)

IronPython parses and runs this code as if it was identical to:

x = {2:3}

for ((i), (j)) in x.items(): print(i, j)

CPython treats these two differently reporting the following error:

x = {2:3}

for [[i], [j]] in x.items(): print(i, j)
...
Traceback (most recent call last):
File "", line 1, in
TypeError: 'int' object is not iterable
