-the plan right now is that this will be an STC forth.
-if this proves Too Complicated To Deal With the plan may be changed
-to a DTC forth instead.

-### words to bootstrap from
-i want to make the kernel reasonably small,
-especially if i add an assembler.
-but obviously we need *something* to bootstrap from.

-- `!` (`val addr -- `): store a 64 bit word
-- `@` (`addr -- val`): fetch a 64 bit word
-- `c!` (`byte addr -- `): store a byte
-- `c@` (`addr -- byte`): fetch a byte
-- `:` (` -- `): compile a word from the current input source
-- `;` (` -- `): stop compiling the current word
-- `parse` (` -- c-addr u`): parse a word from the *forth init* (see footnote)
-- `find` (`c-addr u -- ?lfa flag`)
-- `interpret`: the stage 1 interpreter
-- `latest`: a variable, the latest defined word
-- `state`: a variable, determines current mode (interp./compiling)
-- `>in`: a variable, offset from start of forth init

-on `parse`: i don't want to deal with file access and stuff from the kernel.
-so this word will be Upgraded in the forth init to read from a file.
