I didn’t set up any advanced structural editing in neovim and I don’t recall any such features existing in DrRacket’s editor. The only reason, as I understand it, for using Emacs is this much vaunted ability to evaluate expressions in the editor that are run by a running interpreter process. It was cool to experience but hardly earth shattering or a decent reason to learn the forest of chords, modes, and metas of Emacs… And as far as I could tell, it was just about sending some text to the interpreter via a pipe. It doesn’t seem like something that should require a brand new editor or a complex, custom configuration of an existing one to accomplish.
