If you're not too concerned about 'polish', you could add a __index hook to 
the global table which picks up identifiers of the format HxFFFF or similar 
and returns the appropriate value. You'd probably want a __newindex method 
which complains if someone tries to assign to such a value (which might be a 
performance hit depending on your use of globals, but maybe could be turned 
off in final builds). It would still be possible to redefine the constants 
locally though, but it seems unlikely that anyone would... if nothing else, 
most people use all lowercase for locals.
