WHOA! No type in _deep_check
This should never happen! Please contact the author immediately!
# Looks like your test died before it could output anything.
This should display an error message saying is_deeply() can't handle function refs instead of a generic WHOA. Do the same for typeglobs.
Also document the behavior of is_deeply wrt function refs and globs, that it only looks to see if they're the same reference but this may change in the future.
