Oooh interesting. This is kinda like breaking out of a sandbox, and I
know there are people here who are experts at that. However... I'm not
entirely sure how to get a backtrace, when you don't have any built-in
exceptions! In Python 2, I can define an old-style class and raise
that. However, with the removal of __builtins__, Python throws a bunch
of errors about restricted mode, so I'm really not sure where to go
from there.
