But this is precisely what env does in the first place, so you might as
well just left the bangpath alone.

My point was not that using the (very common, and widely recommended)
bangpath

	#!/usr/bin/env python

won't work, it's just that which Python interpreter it finds depends on
the PATH (because that is precisely what env does).  If you have
multiple intepreters installed, then you may get unpleasant surprises if
you're relying on finding a particular one, since PATHs will vary widely
from interactive shell to cron job to CGI script.
