Actually, he can ;) I recently found a technique that can be used to have multiple XCLASSes of the same class. But of course if two XCLASSes override one method, only the last one will be used.

There is a library called adodb_lite. It very cleverly implements dynamic subclassing. Very nice idea but if typo3 extension want to use this, they will have to write a bit more than "extends tslib_pibase".
