It would fail with a TypeError because the relevant slot in the type object 
was NULL - the TypeError checks aren't shown for simplicity's sake.

This behaviour isn't really any different from the existing PEP 343 - the only 
difference is that the statement looks for a __with__ slot on the original 
EXPR, rather than looking directly for an __enter__ slot.
