I am completely and absolutely with you. But I am just being  
pragmatic right now, and I know most people on this list want mutable  
sequences now... One thing we could do is call all of these classes  
BCMutableSequence, BCMutableDNASequence,... and not use the name  
BCDNASequence,... But I think we will have mutable/immutable  
sequences real soon now. I want to work on that!! I feel exactly like  
you, that we need these immutable sequences to ensure better  
performance.
