Well, that's not good news at all :(

We should really try to find a solution for this situation. You have 
contributed quite some code and it would be a shame to see you leave 
because of this. I guess in your own project that uses BioCocoa you 
could always create your own subclasses of BCSequence to suit your 
needs, but that's a half baked solution, I admit.

My understanding is that the main reason you prefer the typed 
sequences, is that you can avoid sending the wrong type of sequence to 
the wrong operation, is that correct?  Because this is unavoidable for 
untyped sequences, we should do our best to find a solution for this. 
Alex's suggestion, using the symbolset, seems a good step forward. On 
the other hand, untyped sequences make implementing the 
immutable/mutable classes much easier.

John, I am sure I speak for the others too that I would hate to see you 
leave, so again, we should try all our efforts to come to a good way 
out of this.
