Does anyone know if this works?
I type M-x geiser in Emacs 27.1 using Geiser packages from MELPA. I then C-x C-f t.scm and try evaluating an _expression_ (+ 1 1) using C-x C-e. Emacs responds that there is no Geiser REPL for this buffer and to try M-x geiser. All M-x geiser does is spawn the MIT Scheme REPL and does not allow evaluation of arbitrary Scheme buffers.
Any ideas whats going on? Perhaps I'm using this wrong?
