I can only speculate, but I would guess the latter.  What I can think of  
is there may be multiple keys for the same symbol (for example alises, or  
fully qualified names).  But even those should be enumerable.

I think the tables themselves are simple hash-maps, but the layers and  
shadowing is where the problems lie.  I don't have a very educated opinion  
on this, so it may be something else entirely.
