Good point. On my machine at work (Solaris), Python 2.4 seems to send its raw_input prompt to stdout, not stderr:

% python
Python 2.4.2 (#1, Feb 23 2006, 12:48:31)
[GCC 3.4.1] on sunos5
Type "help", "copyright", "credits" or "license" for more information.
>>> raw_input("?")
?z
'z'
>>>
ink% python 2>/dev/null
>>> raw_input("?")
?sdf
'sdf'
>>> ink% python >/dev/null
Python 2.4.2 (#1, Feb 23 2006, 12:48:31)
[GCC 3.4.1] on sunos5
Type "help", "copyright", "credits" or "license" for more information.
>>> raw_input("?")
wer
>>> ^D

Same for 2.6a0 on my Mac at home. Mike, are you sure about it prompting to stderr? If so, what's your setup?
