   That wouldn't work. Shebang line accepts one and only one parameter.
There are operating systems that allow more but they are exceptions.

$ cat test1
#! /usr/local/bin/python -x3
print "Ok"

$ ./test1
Ok

$ cat test2
#! /usr/local/bin/python -x -3
print "Ok"

$ ./test2
Unknown option: - 
usage: /usr/local/bin/python [option] ... [-c cmd | -m mod | file | -]
[arg] ...
Try `python -h' for more information.

$ cat test3
#! /usr/bin/env python -x3
print "Ok"

$ ./test3
env: python -x3: No such file or directory

$ cat test4
#! /usr/bin/env python -x -3
print "Ok"

$ ./test4
env: python -x -3: No such file or directory

$ uname -rs

           Programmers don't die, they just GOSUB without RETURN.
