Beware: this may depend on whether GNU readline is enabled or not --
under many circumstances, raw_input() calls GNU readline instead of
using sys.stdin/stdout.
I do agree that if there are any conditions where it uses stderr
instead of stdout those are mistakes.

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?
