If anyone wants to experiment with this lib + yaegi interpreter I put up a trivial example at [1]. Composing scripts with LSP support and such might be doable with a proper abstraction, in the example a main package with a main function is required. Interpreting might break some functionality for `script` so perhaps rerunning their test suite with yaegi is a good idea if you get serious about this.
