Here are solutions I have used in the past on other Lisps for this sort
of problem. They may (or may not) fit your situation:
1. Write the code out to an external file and load it. Not really much
different that calling eval. Each file has a unique namespace that
I use to keep the bookkeeping straight.
2. Create a parser that generates a series of closures. One can call
this parser at run time to create a tree of functions and then call
the function at the root of the tree to execute your code. Hmm,
that wasn't a very clear explanation. SICP talks about this
technique if you're interested.
I prefer technique #2, but I've success with both.

BTW, Clojure doesn't have an interpreter - all the code is compiled.
You could, of course write your own interpreter if that's what you mean.
