Sound reasonable! So if an extension wants to use "auto-loading", it 
just has to stick to the naming convention. If not, it uses the "good 
old" require_once(...) call.

There are some other things that has to be cleaned up on that occasion, 
e.g. the classes in typo3/classes/ which seem to have been introduced 
for the new backend, but are somehow "lost" in that subdirectory. I 
would rather call that subdir "backend/" and the files 
class.backend_modulemenu.php and the classes "backend_modulemenu" etc.

Also the *.inc files in typo3/. This is a bit difficult, because also 
here the class names would have to be changed (incompatible change in 
regard to XCLASSes). E.g.

typo3/class.file_list.inc contains class fileList.

Correct would be:

typo3/class.filelist.php containing class typo3_filelist or something. 
Or make the typo3/ classes an exception, but then either no auto-loading 
or make that extensions known to the auto-loader.

Cheers,
