Only trying to at least correct the current situation, which I consider a
bit of a mess, personally. (Although it seems others share my view.)

Sounds interesting as well and I can very much see the advantages of such
levels and their methods. Especially in the i18n/l10n work I do.

Actually it seems Java already has a lot of similar methods.

Well, your ideas and seeing Java's stuff actually got me excited to work on
these kind of ideas, next to my datetime revamp.
What would the chances for inclusion in Python be if such a PEP + code would
be presented Guido?
