Thanks for reporting this. I've fixed this by avoiding the change to
"pass" when symbol == "eval".

I don't know that that is intentional. I'd say that, like for the
built-in compile(), the valid values for symbol should be "eval",
"exec", and "single", and the docs ought to be updated (I didn't fix
this).

Cool.
