+Core words
+
+This section contains arch-independent core words of Collapse
+OS. Those words are written in a way that make them entirely
+cross-compilable (see B260). When building Collapse OS, these
+words come right after the boot binary (B280).
+
+Because this unit is designed to be cross-compiled, things are
+a little weird. It is compiling in the context of a full
+Forth interpreter with all bells and whistles (and z80
+assembler), but it has to obey strict rules:
+
+1. Although it cannot compile a word that isn't defined yet,
+   it can still execute an immediate from the host system.
+

+All of this is because when cross compiling, all atom ref-

+This unit is loaded in two "low" and "high" parts. The low part

+part is the "sensitive" chunk and contains "LITN", ":" and ";"
+definitions which, once defined, kind of make any more defs
+impossible.
