I'm not sure I understand what you mean by everything.

whole interface/abstract/class type hints mechanism was added for the sole reason of enforcing prototypes, and effectively, it is pretty much

Concerning interface/abstract classes I can see you reasoning for enforcing the prototype. Personally I don't feel like using interfaces and abstract classes but as it is implemented in PHP5 it should be done right. Make whips and chains people suffer fully from their bondage addiction :-) For class type hints (this is specifying the parameter type in your function definition, right?) I think it should be enforced for *calling* but not for extending. A specialized class often leaves out parameters of the generic base class. E.g. db_record_foo may extend db_record which takes the table as an argument which will always be foo for the specialized class and hence left out there. Does that make sense? - Chris
