[New-bugs-announce] [issue7423] nested generator expression produces strange results

[bogklug]

New submission from bogklug <bogklug at gmail.com>:

The first of the two maps below gives strange result due to the nested
generator expression (I guess it should give the same result as the
second map).

In [1]: map(list, [(x+y for y in 'c') for x in 'ab'])
Out[1]: [['bc'], ['bc']]

In [2]: map(list, [[x+y for y in 'c'] for x in 'ab'])
Out[2]: [['ac'], ['bc']]
