Feature Request: Support for Cross-referencing

[digikar99]

Hello, a query came up in r/lisp that might be solved through support for cross-referencing.

From the Alive documentation, I don't see this is supported yet. See https://slime.common-lisp.dev/doc/html/Cross_002dreference.html for the SLIME equivalent.

It'd be great if this could be added!

I do plan on adding this. It got put on the back burner because the SBCL calls are a little weird. I'll need to dig through the swank source and see what they do with it.
