   Yes, one can write
#! /usr/bin/python -O
   This works. The OS (exec system call) splits the string into a program
(python) and a single parameter (-O), and python knows how to handle -O.

   The problem with
#! /usr/bin/env python -O
   is that exec splits it into a program (env) and a single parameter
(python -O) and env doesn't know how to run "python -O".

   I doubt it. It is env that doesn't know how to run "python -O" in my
example, not python's problem.
