[Python-ideas] Re: mro and super don't feel so pythonic

Every feature means making an arbitrary choice that may or may not be what the programmers wanted.

I don't think that's what greg meant. It's not an arbitrary choice between multiple possible features that would cover the same need. It's an arbitrary choice that the C3 feature itself makes, and the programmer is left guessing what that choice was, unless they can take the time to learn C3 in depth. Which most people don't, so they are left guessing. And since the feature doesn't tell what it does, from within the language itself (or in other term, reading the program doesn't tell you what it does), it's fair to say there's some guessing involved in it, for most programmers.
