A common misconception is that Mac OS X no longer uses type/creator codes.
It is true that Apple appears to want to phase them out, but they are still
there and still work, even with Cocoa applications.

My feeling is that this excellent technology should be preserved and if
enough developers keep using it, maybe Apple will have a change of heart.

So how about some brave person implementing it in the OS X version of R :-)
