I don't understand how interfaces are connected to my proposal, please
explain.
Personally I don't need the strict OO checks for matching parameter
lists at all, but as long as they are E_STRICT (or the like) I have no
problem with them being done. Nevertheless I would like to relax them
just a tiny little bit for signature changes not having an impact of
object compatibility.
That's why I posted two use cases where the checks IMHO go too far and
added a patch to change that.
