It is a newer idea of how to do things.

Glad I'm not in this boat alone!
I almost have a sneaky suspicion that it has something to do with the
__toString()
I've noticed in the past I couldn't do somethings that I normally could do in
custom functions. think it had something to do with constants but then that
was when I didn't have much experience with php5 objects so it's very likely
that was just stupidity on my behalf.
Not played around with it too much since then however. So I guess nows a
better time than ever. hopefully I can duplicate this behavior in a smaller
class that I can just post to the list.
