Any chance of adding Steel?

Steel is an embedded Scheme interpreter, and it'd be interesting to see how it stacks up.

+1. I've been keeping an eye on discussions surrounding Helix's upcoming configuration/plugin system, where the idea seems to be heading toward a Scheme format using Steel. I'm not a big Scheme fan, and I'd like to see how it stacks up against these other options (e.g. Lua with mlua)!

PR is welcome :)
