How much slow down will that be compared to the rest of the method?
Most methods iterate over the sequence, so that will probably take much
more time compared to one call to check the type.

I agree with that. The class cluster design still has the same issues
as the current code (type check yes or no, return values, etc), and
there are no real big advantages (at least I don't see them :). It's
good that we keep talking on this subject, though, because it is the
core of BioCocoa, and we all should feel comfortable with whatever we
eventually decide on.
BTW, how about a class cluster for BCSymbol???? ;-)
