A PEP for a mutable bytes type was composed but withdrawn two years ago: http://www.python.org/peps/pep-0296.html
Another was composed (status unclear) in 2004: http://www.python.org/peps/pep-0332.html It was mentioned on python-dev in 2004 (http://python.fyxm.net/dev/summary/2004-08-16_2004-08-31.html) and 2005 (http://www.python.org/dev/summary/2005-10-01_2005-10-15.html) with the latter discussion mentioning that is a likely thing for 3k. Does anyone know if a well-coded and tested implementation of such a beast exists now? Strings make me sad. -Mike -- http://mail.python.org/mailman/listinfo/python-list
