One compiler improvement that has been on the TODO list as long as I
remember is

Enhance the compiler so that it can inline local functions.

(Using local function involves copying the closure object ATM, avoiding
that would be very nice).

I don't think type-informed optimizations would be easy to do in CLISP.

The success of your project depends on your commitment, which depends on
your interest.
Please pick whatever excites you.

Thanks.
