Mostly I think nesting many layers of partial(), or optimising the implementation with that in mind will not be a win for clarity, therefore a net loss however fast you can make it. By the way, I think 'right curry' is just a broken idea from the point of view of code readability. (I know the n'th argument is '2', but 'n' will depend on how many arguments are passed at run time!) The PEP doesn't propose to implement such a monster, or call partial() a curry at all, let alone a 'left' one. Peter Harris

Freezing for alpha3 - trunk FROZEN from 2004-09-01 13:00 UTC
by Anthony Baxter 01 Sep '04

01 Sep '04

I plan to start alpha3 in about 24 hours time. From about 12 hours from now, the trunk should be considered frozen - that's starting at about 1700 UTC on 2004-09-01. If your name isn't Anthony, Fred or Martin, please do NOT check in while we're doing the release. Really. Really, really, really. I'm cc'ing python-checkins as well this time, as a few folks missed this last time. The trunk will stay frozen until about 6 hours or so after the release is done - this makes it easier for me to do an emergency brown-paper-bag release in the case of a cockup <wink> Thanks, Anthony
