@pez I'm interested in contributing to calva by exploring the possibility of supporting vscode's CodeLens feature for clojure code. Since calva already enables "Go to definition" support in the editor, allowing navigation in the opposite direction (function definition -> function usage) sounds like it should be possible. Any reason you think that it's not possible, before I jump into the calva source?

Refactor-nrepl provides an op for that. Replant uses it

Great! I'll look to that as an example for how to implement it.

thanks for the info
