ISTM the name-as-invoked is a named arg (script file name -- relative or absolute)
whose meaning is relative to the cwd of the running python interpreter instance, and
therefore should not be resolved through $PATH, unless that is what the python interpreter
does (which I don't think it does).
It might be an interesting command line option to pass to python, though, letting it do
a search according to whatever search path might make sense. I could see using the system's $PATH,
but I could also see a more limited search in the python tree. Maybe both options.
BTW, this seems to be a minor buglet:
[16:25] C:\pywk\clp>python -c "import sys,os; print os.path.realpath(sys.argv[0])"
C:\pywk\clp\-c
vs.
[16:25] C:\pywk\clp>python -u -c "import sys,os; print os.path.realpath(sys.argv[0])"
C:\pywk\clp\-c
(note that -u is excluded, as IWT -c should be).
