Yup, and I've seriously thought about something like that. Two issues:
my measurements show that using a jar doesn't really improve runtime
that much. The other is that, lein works sorta-kinda like make. I like
make. But as I just posted, I don't use it for one-file programs or
programs that don't need building. That doesn't seem to be possible
with lein.
