But it seems other people might think this means "a sequence with the first element being an integer, and the second a float". The BDFL seems to have yet a different idea: http://mail.python.org/pipermail/python-ideas/2012-December/018129.html This is clearly material for a separate PEP, wink wink, nudge nudge. To the point though. Based on this, and the fact PEP 8 currently disallows annotations within the standard library, I came to the conclusion that currently we should not include the annotation-driven form.I generally lean towards returning the undecorated function, so that if you say: @func.register def do_int(foo: int): ...Me too. The PEP has been updated to specify that explicitly.
So with this decision made, are there any open issues left? Or can we invite Guido back to the discussion? ;) -- ~Ethan~ _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
