Yes but B::test() was called to start the call chain and in this
situation I want the B::test() method to decorate A::test() and it just
isn't possible without allowing parent:: to forward the called class or
introducing a new keyword.

I (and many other people) don't feel the need to do things this way and
it is slightly frustrating to see a patch implemented to allow us to
'sort of' do it cleanly but ultimately misses the mark. Especially when
it is probably a relatively minor change to support what we are asking
for. This is also a terrible argument to use against a new feature...but
that's an entirely separate matter.

By loose inheritance I mean extending and overwriting a method while
changing that method's parameter list.

I apologize, I grabbed php6 and appear to have not remembered things
quite right. I thought that you could not change the parameter list of
inherited static methods which is not the case in php6. Although you
WILL have a problem if you program to interfaces. If static public
test() is declared in an interface that  A implements then you won't be
able to change the parameter list in B.
