I agree it should be a SyntaxError - I believe the AST compiler actually raises one in this situation.

Could someone add a test for this on the AST branch?

BTW, it looks like doctest is the way to go for SyntaxError tests. There are older tests, like test_scope.py, that use separate files with bad syntax (and lots of extra kludges in the infrastructure to ignore the fact that those .py files can't be compiled).
