:-) There are lots of possibilities here. You could "compile" a format string into a closure, and save it in a hash table. You could compile it to Scheme and then compile that procedure. You could recognize some common degenerate cases. Dunno! In this case I would compile the string into a closure. Seems pretty cheap and it would kill the dispatch overhead.
