Well, yeah, that's the thing- getting maximal performance out of
clojure seems to require a degree of expertise and patience tha

Hrm, I've never found it all that hard to type "ant" when I want my
code compiled. :p
I will admit, when I first used ant, I was scared to death because of
stuff I had heard about it. I actually had fun using it.

Fair enough. However, what I had in mind was that I could simply
compile one namespace that would then act as a sort of 'bootstrap

manually all the time.
Rayne's suggestion
I suggest writing a short ant build file to automate building your
project, that way you don't have to type all that stuff! I wrote a
little build.xml file for a project I'm working on. You should be able
to extend it to fit your project. I also suggest looking at Clojure
and Clojure-contrib's own
