Pretty much every 20 year old codebase is a mix of terrible stuff. The exceptions are rare and usually involve a strong handed dictator who is willing to make cleanups from time to time.

You're lucky it isn't Fortran and a homegrown (crappy) macro language.... You can't fairly judge Scheme or C from a legacy codebase unless you judge every other language that way too.

I'm judging only from its debugging capabilities - and it looks like even now there's no (open to all) way to do that. Compared to that, C even if that's 20 years old code too, has some great debugging tools for it.
