[Python-ideas] List Revolution

[Matt Joiner]

Well it makes complete sense to me. Furthermore, Python even properly
supports the style of conditional he uses. a <= b < c IS a great way
to do things. 0 based indexing IS right for computing. Not sure if
you're trolling or I'm not counter-trolling... -.-

EWD is the man. Dutch programmers in decades to come have a lot to live up to.

There's no reason to think that being a good mathematician would make one also good at designing a user interface, and that's what a programming language is--a user interface for highly advanced users. Other than "Go To Considered Harmful" everything I've read of his about programming has been wrong. (Correctness proofs, really?) And much of that wrongness stems from EWD's false belief that programming should be the same as math.

But the reason not to change is because 0 is a well entrenched standard so most programmers are more used to it than to 1. In other words, it's the standard because in UI design you stick with what your users will expect. It has nothing to do with some arcane mathematician's gobbledygook writings about greater than and less than signs. Programming language design is the art of making something that helps humans work more efficiently, not some pure mathematics descended from Platonic heaven.
