Comment:
The problem is that the code expects IMPORT_NAME immedeately followed by
a sequence of IMPORT_FROMs. That has changed now that IMPORT_FROM
puts the result on the stack.

A fix that appears to work for me is to set lastname to None only on POP_TOP
instructions. But I'll leave doing the actual fix to someone more knowledgeable than
me on the code that from x import y can generate.
