That's really a question of the semantics of the program one  
generates, is it not? I wouldn't expect ST to do that for me.
I know I'm dealing with words, because that's what ANTLR spews out.  
If I wanted to do bytes, I'd had to convert that myself. If ANTLR  
would ever change to do bytes, my code
would break nonetheless. Nice, because then there's no justification  
to do arithmetics in ST, anyway ;)

You're right, of course it should be consistent across the board. I  
thing too much in terms of objects and methods nowadays...:)
