I think trying again, we actually have this currently: position-only, no default position-only, early default position-or-keyword, no default position-or-keyword, early default keyword-only, no default (weird one that I've definitely never used before just now) keyword-only, early default Under the proposal we'd add: position-only, late default position-or-keyword, late default keyword-only, late default It's not nearly as much as I was thinking. Of course, it *is* a 50% increase in the number of parameter types. Still, that's not the main reason I oppose the PEP. I don't really think any of these are fully orthogonal. But the number isn't absurdly large. Hmm... I suppose `*args` and `**kws` are also different types as well. Of course, defaults don't make sense for those. So maybe eleven rather than nine (and lower percentage increase). -- Keeping medicines from the bloodstreams of the sick; food from the bellies of the hungry; books from the hands of the uneducated; technology from the underdeveloped; and putting advocates of freedom in prisons.
