Ok, happy bikeshedding. I'm outta here until that's settled. :-)

Łukasz, are there any open issues? Otherwise I'm ready to accept the PEP. There's one. Quoting the PEP: "The dispatch type is currently specified as a decorator argument. The implementation could allow a form using argument annotations. This usage pattern is out of scope for the standard library (per PEP 8). However, whether this registration form would be acceptable for general usage, is up to debate." I feel that the PEP should explicitly allow or disallow for the implementation to accept dispatch on annotations, e.g.: @func.register def (arg: int): ... versus @func.register(int) def (arg): ... -- Best regards, Łukasz Langa WWW: http://lukasz.langa.pl/ Twitter: @llanga IRC: ambv on #python-dev
