I still had this patch in my queue, but I wasn't sure if it was
obsoleted by something else...

While I don't really mind having language checks in the expression
evaluator, it seems like this particular error condition is something
that could be detected in the C parser.

Also, I think the C++ rule is more complicated.  I did not look through
the standard to find it, but g++ at least gives an error for a simple
scalar "x++ = 5".
