I really loved the Rails console for developing web apps. Write a few lines on the REPL, then past them in an app/model file. Knowing Rust (and other strong typed langs) I understand that it is not so easy to implement this workflow for these languages. But looking at this project I kind of have new hopes. With the strong languages it should even be possible to have intellisense-like completion/suggestion available on the REPL! Would it be, eventually, possible use Evcxr for this purpose?
