It's not quite like that. The compiler implements Scheme and is written in Scheme.
Nothing funcy and no custom extensions required.And it is very portable: the boot image for a new platform can be cross-compiled. That's what I'm about to do: compile boot image for BSDs on Linux (or Mac OS, doesn't matter).
This is exactly the same as in case of SBCL (lang/sbcl), except that in SBCL in pkgsrc is bootstrapped with help of lang/clisp. But in case of ChezScheme, it can't be bootstrapped from other Scheme implementations (I am not even sure there are any that are fully R6RS-compatible). On the other hand it's better than SBCL,
because the bootstrap image can be cross-compiled.Actually the same problem exists for lang/go which is bootstrapped from long/go14.
So this is very generic problem. ChezScheme is not special in any sense.
"You" is a generic third party pronoun here... Joerg
