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($a=1);
}
interface B{
function foo($a="hi");
}
class C implements A, B{
function foo($a=default){} //what would be the default value?
}

Cheers,
Robert
