This actually seems like it would be very helpful to use for some factory
functions as well. If @ could be made to work on variable assignment
similar to how it does on function definition then the following would be
possible and make code a bit more DRY:
# currently: LunchBox = namedtuple("LunchBox", "spam eggs")
@namedtuple("spam", "eggs") LunchBox
LunchBox(eggs=2, spam=4)
# LunchBox(spam=4, eggs=2)
# currently T = TypeVar("T")
@TypeVar T
The variable decorator would be in full control, just like function
decorators so I'm sure some even nicer abstractions could be
created. Perhaps instead of turning
UserID = NewType("UserID", int)
into
@NewType(int) UserID
it could be
@NewType UserID: int
