Discussed here:

I'm working on a fix, hopefully within a couple of days.

Hobbit is a whole-program compiler. Guile needs an incremental,
embeddable compiler, with source information, and a repl, etc etc.
Apples and oranges, to a rough approximation.

Guile will be fast, but it will take a couple more years. In the
meantime, it is getting better, but if you are in a hurry for some
reason, perhaps some other scheme would suit your needs better.

Cheers,

Andy
