-~ This is a temporary holding place for stuff that probably should be in
-~ core someday, but only after carefully considering whether to rewrite it in
-~ assembly. Most of it originally came from boot_source in quine.asm.

-~ Now some fancier stack combinators.

-~   While it might be nice, for performance reasons, to do these in
-~ assembler, for now it's more important to have them at all.

-~ Standard Forth doesn't have equivalents of our ndrop and ndup. The HP
-~ calls them DROPN and DUPN but that doesn't go well with ie. 2dup or 3roll,
-~ so we do it like this.
