Hi Terry,
Thank you. Any idea why setlocale (a *setter*) returns something other than
None? (this question is not related to the (None, None) thing of getlocale,
just curious). Would it be a good idea to put this setlocale line in site.py?
Or should it be in __init__.py to make the code more portable?

So then I would have all the locale categories of the 'bare' locale (sorry, I
don't know what else I should call it), except for LC_CTYPE, which is derived
from my system. So in LC_NUMERIC I'd still have the en_US period/comma for
decimal/thousand grouping, respectively, but I switch to the nl_NL LC_CTYPE. I
doubt if it matters, but still: will this not introduce an ueber hard-to-find
possible bug when I use re.LOCALE?

What is the difference between getlocale and getdefaultlocale anyway? The
docstrings are even partially the same. The notatation of getlocale appears to
be OS-specific ("English_United States" in Windows) and not Unix-like (cf.
getdefaultlocale: en_US)
