I like Georg's idea of having an immutable bytes subclass. b"abc" could then be a shortcut constructor for this subclass. In general, I don't think it's a good idea to have literals turn into mutable objects, since literals are normally perceived as being constant. -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Source (#1, May 05 2007) >>> Python/Zope Consulting and Support ... http://www.egenix.com/ >>> mxODBC.Zope.Database.Adapter ... http://zope.egenix.com/ >>> mxODBC, mxDateTime, mxTextTools ... http://python.egenix.com/ ________________________________________________________________________ :::: Try mxODBC.Zope.DA for Windows,Linux,Solaris,MacOSX for free ! :::: eGenix.com Software, Skills and Services GmbH Pastor-Loeh-Str.48 D-40764 Langenfeld, Germany.
