Ah, nice! It seems most we came up with is already in there. Even Any 
which I use in my project but didn't think of putting in the package is 
there. No use anymore for a new package now, I guess. On the other hand, 
I can't find the comm, trans, coerce, subst and resp. Would it be an 
idea to add those to your package?
