RR's own constants are global because they are part of the language 
so do speak. As such, they are defined in the engine. That makes them 
a different beast than constant defined in your scripts.

Replicating constant behavior at global level has been discussed 
quite a lot in the past, and not only on this list, but... it is a 
lot more complicated than it seems at first glance. So, for now at 
least, there is no way to make a global behave like a constant 
through declaration. It is up to you to designate some globals as 
global constants, like using a different prefix than for global 
variables.
