[Biococoa-dev] Optimizations

Crap, I didn't even think of that.  The gains are really substantial,
literally cutting the time for a translation in half.  I could probably do
some function pointer lookups and use those to cut time down an equivalent
amount, but (IMHO) they make the code incredibly difficult to follow.  Plus,
never really having used function pointers, I doubt I'd be any good at
maintaining them.  The other option would be to trap things with some
#ifdefs, but that does ugly things to code readability as well.

Is there any sense of who uses BioCocoa?  If nobody much is doing anything
with it using GNUstep, then this won't bother anyone.

Thanks for pointing this out -


PS - what area of biology do you work on?  We seem to have a fairly broad
spectrum already within this small group.
