why no "do : until"?

Guido actually implemented it a few years ago, but backed off when somebody
said they had a program that already used "indexing" as a vrbl name.
Keywords suck <wink>.  Before 2.0, Thomas Wouters implemented it again
without making "indexing" a keyword; that's Python patch #101138 on
SourceForge, and you can read its history there.

Na, in real life it's pretty much a yawn.  Yes, it speeds up

    for i in range(len(a)):
        pass

enormously, but the more "pass" gets replaced with useful work, the less
significant the looping overhead.

Nope!  First link didn't resolve; the other two did.

Guido will die before he allows

    A \ #+

as a way to spell "sum of all the elements in A", though.
