Writing serialization code. It ain't too nice, should look at betters ways of doing it, just using a piece of malloc'ed memory for a buffer and some serialization primitives - which I should do better.
Wrote a faculty function on longs, debugged it and it got accepted. Got too much boilerplate code now on various types in the C runtime, thinking about removing references to uint8, .., sint64, hi_char, stuff like that - though some people might just like that approach, not sure. Principally, I only need C types and the Hi internal word size.
I should serialize w.r.t. to a serializer, and make it possible to drop in different ones.
