What would happen to the instanciated objects?
Only allowing class unloading for classes that have no instantiated objects would be an option.
And how would you know if it'd been instantiated? Even if you recursively looped through every variable hash from EG(symbol_table) on down, there'd still be the possibility that one or two objects would be hiding in a resource somewhere (i.e. php_stream_context).
Is there a technical limitation to loop through every internal hash which could possible hold an instantiated object?
If there would exist functions like - class_has_instanciated_objects() - class_get_instanciated_objects() I guess noone would expect them to be quick or fast.
Of course there's the fact to respect the class hierarchy which adds complexity.
I can imagine that optimizers and such would have problems with it. But albeit, technically?
