Constructors are definitely not virtual methods. So no reason to check signature.
Moreover, this is a non sense to declare constructors in interfaces or abstract
constructors in abstract classes.

I think we should just drop the signature check. Interfaces may
include a signature for better readability but the engine should ignore
them. PHP4 class trees work fine even without strict inheritance

Hello Timm,
well for normal methods we must do that. The derived class must support the
same signature that the base class supports. In you example that would only
work if the derived method would have a default parameter for the additional
parameter:
