I don't think there's much point to this (at the moment) because I don't
want to relearn C (at the moment) and Nim is available (at the moment.)
Really, I'm trying to do away with the entire relationship of C et. al.
to the underlying machine. (For instance, Nim gives you a much nicer
relationship, without the vast distance that, say, Python imposes.) I
should really look at other compiled languages, like Ocaml or Julia.
