In trying to make APL my primary PL, I have been playing with April[2], a subset of APL in Lisp, another old favorite PL. It is a blast. I am honing both my Lisp and APL skills, and they seem to cover each other's weaknesses for easier adoption in the general programming world.

I wanted to hit the runtime repeatedly with as little overhead as possible. So VVM has no type look-up, multiple operands per instruction, and a cache-efficient IR. The sum() operand for the above example is invoked directly in a loop almost as fast as hand-written C++.

VVM has its own assembly language [2]. I have blog post that explains some of the design choices [3].
