Yep.

Now, want to have your mind blown?

$ cat ~/tmp/test
#!/usr/bin/python

def hello():
  print "Hello world!"

hello();

$ python ~/tmp/test
Hello world!

$ perl ~/tmp/test
Hello world!

If you don't set it in #! you, or somebody else, will forget to pass -w to

the test is running differently from in "make test".
