I think, there should be no difference between them. The keyword itself is a 
string. If a string doesn't have non-keyword characters, it can be used 
without quotes.

My opinion on this is that we shouldn't do any magic, and that "yes" should be 
the only "yes" but not "1" or "true". For "magic" comparison I'd write 
something like boolean(oneway)=true, like in eval().

Case insensivity is bad, I think.
