Yes, but not there's no impact on speed and that's what Valdimir
was referring to.

Note that I want to redesign the Unicode database and ctype
access for 2.1: all databases should be accessible through
the unicodedatabase module which will be rewritten as Python
The real data will then go into auxilliary C modules
as static C data which are managed by the Python module
and loaded on demand. This means that what now is unicodedatabase
will then move into some _unicodedb module.
