Are we sure we want that? Raising from something not an exception seems
counter-intuitive (None being the obvious exception).
I'd want to allow
"exc.__cause__ = Ellipsis" to reset an exception with a previously set
__cause__ back to the default state,
Already done. :)
at which point the synonym
follows from the semantics of "raise X from Y" as syntactic sugar for
"_exc = X; _exc.__cause__ = Y; raise _exc"
I can see where it would make some sense that way, but it still seems odd.
