Cool to see languages besides C running on small hardware. I would guess that memory consumption, not speed, is the limiting factor vs. C in many applications.

Cool to see languages besides C running on small hardware. I would guess that memory consumption, not speed, is the limiting factor vs. C in many applications. I skimmed through the source code and couldn't find a way to define heterogeneous packed data types (i.e. structs). That would be a serious turn-off for me. Cons cells take a lot of extra space. At least it has vectors.
