Hello Jessie,

Maybe this new discussion gave one hint. Aliases could be solved with a flag. Just copy the classwith a new name into the classlist again and flagit as copy. Maybe the original class gets a list of the copies of the copies a pointer to the original but that would be an implementation detail. As soon as that is done importdoes nothingelse then copying classes on a single class table. That said namespaces would, if after all, simply contain other copies to the original classes. In the extremecase we can start with namespaces only being a 'stupid' list. Reflection could then travers all classes to see in which namespaces it was registered. This btw would also fix 3) as the namespace seperator would be a normal sign in class lookup, it would simply be disallowed in definitions of class/interface/namespaces.
Did not notice these further comments until now. Anyways, I originally implemented imports in this way (making copies in class_table and updating the reference count), but then I used another approach because then imports would be request-wide, and I wanted them to be file-specific only (yeah, I know the PHP6 meeting notes said they should be request-wide, but I see this causing many problems to the point where they cannot be used in order to guarantee safe code).
Also, yes, ':' are not be allowed in either class or interface definitions, but they are included in the full name in class_table (e.g. "namespace_name:class_name"). This is how it is currently in my patch.
