Well, let's see.  The first machines I used didn't have a case problem: 
they only had upper case.  Is that case sensitive or case insensitive? 
[They also had identifiers of 3 or fewer characters.]

Then I used some machines with upper and lower case, which were case
sensitive in the language processors I used (favoring lower case).

For that matter, they didn't have a file naming problem...they didn't
use file names.

Times do change.

I happen to prefer case-sensitive languages (that could be the only
aspect of C that I prefer to the related aspect of the Pascals I
used...which had reacted to the advent of readily available lower case
in mid-life by being case insensitive).

So I think Python is currently right in this area, but it isn't
important enough to me to cause me to stop upgrading Python versions
when it changes.  Or argue about.  

[The direction the Unicode source threads are taking might well, but we
still have the BDFL (or bdfl, or bDFL, or bDFl ...) to conrol that...I

I also hope that after the change to case-insensitive Python, we don't
also go through a change to diacriticals-don't-matter Python.
