McCarthy is mentioned for that, but I guess more work on that was done in the Smalltalk and Self context.

Since quite some time most Lisp systems don't use a JIT. They compile the code ahead of time or explicitly incrementally.

I am aware of type hints, but given Lisp's dynamic nature, wouldn't a JIT provide more optimized code than AOT?
