Bug report

Bug description:

Right now we have:

>>> import a as a  b
  File "<python-input-0>", line 1
    import a as a  b
                ^
SyntaxError: cannot use name as import target

>>> from x import a as a  b
  File "<python-input-1>", line 1
    from x import a as a  b
                       ^
SyntaxError: cannot use name as import target

This happens since these cases match these two rules.

One possible fix would be to add NAME to the list of not-matched tokens so that the current rules don't match this case.

However, I have an idea for a slightly nicer error. PR forthcoming.
