Good point.

In the meantime, you could use this Python script instead (name
it pythoni or something)

-----
#!/usr/bin/env python
import sys,os
import os.path

modfile = sys.argv[1]
pystartup = os.environ['PYTHONSTARTUP']

env = os.environ.copy()

modpath = os.path.abspath(os.path.dirname(modfile))
if env.has_key('PYTHONPATH'):
    env['PYTHONPATH'] = modpath + ':' + env['PYTHONPATH']
else:
    env['PYTHONPATH'] = modpath

modname, ext = os.path.splitext(os.path.basename(modfile))

os.execvpe("python",["python", "-i", "-c",
           "execfile('%s'); from %s import *"%(pystartup,modname)], env)
------

Then 'pythoni path/to/script/file.py' will do what you want
(hopefully; this wasn't tested extensively)
