RE: meta-compiler

Hoi Albert,

I can see your thought processes going in exactly the same direction as mine
;)

If the editor is in the kernel, adding a new colour token requires a new
kernel...
Solution : write the editor in colorForth. This is largely done.
So, yes, the editor in the kernel is restricting, and so could be construed
as a negative feature ( IMHO ).

I have in fact added a new colour token - blue - to the cf version of the
editor, just to see how easy it is to do. Its easy.
As for what the compiler does with it - we need the compiler to be written
in colorForth too...

Perhaps Mark could confirm, but I don't think that his colorForth compiler
requires any new colour tokens, although he is patching the behaviour of the
magenta variable.

English tutorial : "historical accident" has only a slight negative
connotation, as in something that happened by chance in the past, and not as
in "road traffic accident" which is totally negative.

A historical accident, is that a negative assessment, i.e. something
that preferably be changed? (This is just my understanding of English).

About my question. Suppose you want to add a color. Now the source
has to be generated by the old colorforth. So its editor must know
that new color?
