[Python-ideas] Regex support code as std lib functions

[Matt Chaput]

I'm not sure where regex is in its long march toward replacing re, but I 
just noticed something interesting: the regex module seems to include 
implementations of some useful functions to support its regular 
expression matching, e.g.:

- Levenshtein distance

- Unicode case folding

Both of these would be useful as fast functions in the std lib. If/when 
regex replaces re, any possibility all the useful functions that support 
it could be added to the std lib in the appropriate modules as part of 
integrating it?

Cheers,

Matt
