thank you! i didn't know clisp had a jit compiler, and i certainly should have thought of abcl, and also you mentioned them in your other comment in https://hackertimes.com/item?id=38933091
how much of a performance boost does abcl get from the hotspot jit compared to, say, interpreted clisp
CLISP has a byte code machine, for which a JIT can be used.
There might be others.
