Hi Brad,
Are you sure about that ? The manual states that this is the normal
behaviour which I find very handy and useful in many cases. I see a lot of
possibilities with this feature, for instance a way to develop some kind of
plug-ins for existing classes without having to extend them.
This can probably lead to some dangerous code but this goes far beyond my
knowledge.
Anyway, if someone aware could give some clarifications on should I rely or
not on this behaviour, that would be very appreciated.
If this behaviour could be extended to support $className::method(), that
would be just great.
