There’s also guile-json, bindings to a C library, but I think it’s
better to have a pure Scheme implementation, and to have it in Guile

I wonder if we should introduce it in 2.0.  What do people think?

This won’t print correctly, unless there’s an exception printer
installed in boot-9.scm (see ‘getaddrinfo-error’ for instance.)  Could
you add one?

Also, I think we need more details about the error: parse error, what
kind, etc.

Would it work to use the parser from (language ecmascript parse),
possibly restricting it?  Or do you think it’s more viable to have a
separate parser because there are too many differences?

Is there a standard test suite that we could test it against, somehow?

Otherwise LGTM.

Thanks, and sorry for the delay!
