interface extend the old interface. Still painful for calling code, but doable.\u003c\/p\u003e\n\n\u003cp\u003ewhat is worse is changing method signature - that becomes virtually impossible.\u003c\/p\u003e\n\n\u003cp\u003ePerhaps we just should not ask extensions to implement interfaces at all. Perhaps we should always provide a base class. We could declare an interface and type-hint against that, if that seems useful. This strategy seems to work reasonable well for Java: for the List interface, there is an AbstractList base class that can be used by code that wants to implement the List interface; this makes it easy to introduce a new ListNG interface with default\/compat implementations in the   AbstractList base class.\u003c\/p\u003e\n\n\u003cp\u003eThis problem checks the boxes for an RFC: it's strategic, cross-cutting and hard to undo.
