I think of the following definition:

function foo($bar = NULL)


To really be two definitions with method overloading:


> function foo()

function foo($bar)


Allowing an inheritor/implementor to choose to not implement the second
signature does not seem logical at all when you think of them this way. I'm
against this this proposal.
