good point.

seems to make sense -- i like this model.  we should think about how we
get the same code into different classes' methods.

sequence db stream is for the "loops," take it.

OTOH, relying on C code will cause many people not to use the programs
(because compilation of C is much harder than just using a Perl module).
Therefore, I think that writing Perl code has much merit.
