Note that BCSymbol objects are uniqued and reused. So in fact a  
BCSequence is an array of pointers.

I don't know what the status was on the BCSequence implementation,  
but one of the "todo" things was to switch from NSArray to C arrays  
behind the scenes, while still exposing NSArray too in the interface.  
But I think Koen did some of that transition??
