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

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?
