This would also remove a lot of code. I see case (in)sensetivity in names of functions/classes/... as being separate from case sensetivity in file names. There is already a problem for those who develop on MS-Windows/Mac and deploy on *nix - a typeo can lead to a failure at run time. The fix is simple, people do not complain that PHP should protect them from this. I am a believer in simplicity, which is part of the reason that I support the idea of removing the complexity of case insensitivity in function/... names. Case folding has a slight speed penalty and does not work properly. It does not fold unicode characters outside the range U+40 - U+7A (ie US ASCII), so best to just forget it. -- Alain Williams Linux/GNU Consultant - Mail systems, Web sites, Networking, Programmer, IT Lecturer. +44 (0) 787 668 0256 http://www.phcomp.co.uk/ Parliament Hill Computers Ltd.
