The PEP does not address the issue of whether the new variation of raise

is clear that raising the default as something else is invalid if there
is no default.
Were you speaking of the original (PEP 3134), or this new one (PEP 409)?
Because at this point it is possible to do:
raise ValueError from NameError
outside a try block. I don't see it as incredibly useful, but I don't
know that it's worth making it illegal.
So the question is:
- should 'raise ... from ...' be legal outside a try block?
- should 'raise ... from None' be legal outside a try block?
