However, the only way said programmer can do that is by looking at
_your_ code, and then changing _your_ code. Wouldn't:

  def foo(bar, baz):
      """...
         Expects:
            bar: integer in the range (0..65535)
            baz: string (used as binary data)
         ...
      """

be much more useful for said programmer? Afterall, we're all adults
here.
