I don't see that tests are fundamentally different
from any other code that wants to call a value-returning
generator and get the value without becoming a generator
itself. So if it's to be mentioned in the PEP at all,
a general solution might as well be given (whether it's
to use a trampoline or just write the necessary next()
and except code).
