I can imagine using a metaclass specialized witch can be activate or desactivate but the cost of decorator call still be here...
I think its will be a good improvement if we can provide a solution for this, and i ask myself if this can be set in interpreter with a flag to activate for exemple and with no performance cost without the flag set, so you will have the choice and a good way to check youre code. To have no performance cost perhaps the best way it's to use docstring and pylint... 2016-11-23 10:10 GMT+01:00 Paul Moore <p.f.mo...@gmail.com>: > On 23 November 2016 at 08:08, François Leblanc <fleblan...@gmail.com> > wrote: > > It's why I'd prefer this integrate in language, but if there no way to > get > > it without performance cost > > I will have a look to a pylint solution... > > The point here is that if there is a way to get it without a > performance cost (I can't imagine there would be, it's got to add a > check for whether you're overriding a method at a minimum, but you may > be able to come up with something) then you can do that within the > language as it stands.
