In fact, now that we have dynamic loading infrastructure, it would be silly not to use it! (This raises issues of having a compiler, optimizer switches, etc., but given the benefits, those issues are minor.) `.el' files are not compiled and loaded on the fly. You have to compile them manually. I would like to see another "level" of this compilation that turns `.elc' files into `.ell' (by way of .c), which you can proceed to load as usual. Of course, the whole thing, being an optimization, would be entirely optional.
