I think you need to build python.exe to work differently
than it does today. I don't believe any amount of black
magic in site.py or sitecustomize.py (etc) would convince
python.exe to "search" for its bar.py argument elsewhere
than in the current directory.
Such an alternate python.exe (it had better be named
differently I guess) might have value, but we don't
have one today.
I think the reason this is not perceived to be a problem
is that people who work on operating systems don't do
it that way. They write, e.g.
$ bar.py baz.dat
and their OS searches for executable bar.py in the PATH.
This works on all Unix variants, and on NT/2000 as well if
you tell CMD.EXE that .py is one of the extensions that
make a file executable (sorry, I forget the incantation
for the latter purpose:-). It *doesn't* work on 95/98/&c,
but then I DID say "operating systems"...:-).
