In my opinion Sean didn't ask whether PHP behaves that way but _why_.

And I don't really see the point either as U::f works with all code 
previously using T::f. Even more so for function V::f($x,$y=false) to 
provide extended functionality to T::f($x) for code which knows about 
it.  And why would changing the default value be ok in your book? But 
then again I'm not an OO purist and I don't (have to) use E_STRICT.
