This would be quite a nice feature, even if this RFC does not pass. Just =
as hint, there are ambiguous case which need to
be considered:

interface A{
function foo($a=3D1);
}
interface B{
function foo($a=3D"hi");
}
class C implements A, B{
function foo($a=3Ddefault){} //what would be the default value?
}

Cheers,
Robert
