Isn't this almost the opposite of "or die"? Unless I'm having a very
bad day, the die idiom is more like a SystemExit, but this proposal is
a way to recover from expected Exceptions.

>>> if not func(args):
... raise SystemExit(msg)
This proposal, with the "a non-dict mapping might not have get" use case:
>>> ((mymap[k] except KeyError then default) for key in source)
means
>>> def __temp():
... for element in source:
... try:
... v=mymap[k]
... except KeyError:
... v=default
... yield v
>>> __temp()
