Yes, we definitely need this for the Scheme!

SLIME, the popular Emacs environment for Common Lisp, uses a backend
called Swank. We should look into how Swank is implemented.

Here's some Swank support for Scheme implementations by one of the
Chicken hackers: <https://github.com/ecraven/r7rs-swank>. I haven't used
these integrations myself, so don't know about how polished they are.
