Is _this_ supposed to happen, too? Ah, I guess to. It's the problem with
using this outside of Zope. :-) I couldn't figure out what it was for.

Yes, I've seen this in stop_words_dict from Lexicon.py.

Uhhh, no, it _is_ implemented. It just didn't work like I'd expect :-)
So it does look lowercase words up. Of course, this is an artifact of the
following point you make:

This makes sense:
>>> s = Splitter("Crazy")
Ahhm. Okay. Will update my documentation with this important point.

Fascinating points on i18n and l10n of the indexing mechanism. Makes me
wonder how far the current implementation will go before having to be
rewritten, and if the world will survive east-meets-the-west of computing
But I believe the Splitter could stay the same for western languages, from
what I've seen of the code. Can't really see the ing-cutting stuff here.
