It works. What we cannot do is inheriting a function and specifying
a base class typehint:
class Root {
}
class Base {
function f(Base $p) {}
}
class Leaf {
function f(Root $p) {}
}
It is doable as the following patch shows:

(the patch me be a little bit outdated though).
I guess this can pretty good wait for 5.1.
