-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.
