To replace an interpreter by a JIT compiler means more oomplexity and
also more possible problems. (For example, if there are platforms
someday that libjit does not support.) Reading a Lisp interpreter is
very useful for learning.
If the plan is to add a jit and keep the Lisp interpreter as well,
we don't lose its advantages for study, and we can still support all
the platforms -- but we add complexity even more.
I don't think a 3% speedup is worth those drawbacks. Or even a 10%
speedup. A really big speedup would justify the costs.
