I have no idea how to really ask this, but does it uses continuation-passing style [0] to execute expressions? I tried to search for "cps" or "continuation" in the repo, but no luck. I also don't really have the time right now to go dig through the source.

Most languages don't have reliable enough tail call elimination to implement CPS without trampoline techniques to get rid of the excess stack frames, which in turn has a fairly hefty performance impact unless you're using it for something high-level like async callbacks.
