Sorry, I disagree that it is out of scope.  Looking in the current 
directory is fine, when the script is there, but my scripts are seldom 
in my data directories, and I want to run scripts (from the PATH) on 
data that is in the CWD.  I consider this a _very common_ use case for 
using scripts/programs, but then if you want to use py from the command 
line to tweak which version of Python gets used to execute the script 
(if the default one didn't work, for example, and you want to try a 
different one), then suddenly, you have to find the path to the script, 
and specify it explicitly.

Even if CWD is a data directory, and foo.py is somewhere on the path?
