Thanks for the link. v0 cli was written in gerbil scheme (http://cons.io) but I couldn't get it to statically link on linux so I'd still have deps in the form of dynamic libs. Then I found oclif which while depending on node has a lot of what I need and will allow me to ship/iterate faster ... If the spec/features/api was fixed, I'd write the thing in golang if only for the static binaries and cross compiling but it's a relatively joyless/cumbersome language IME, so node for now at least.
