I am running Emacs25 with Geiser (latest version from MELPA, 20180128.1821) and Guile (version 2.2, Debian package). So far it works fine, but when I evaluate a sexp, it will print the result to Emacs' echo area instead of in the REPL buffer. Is there a way to change this behavior? I'd like to be able to scroll through long output, copy parts of it, etc.
I tried looking into the configuration menus, but found nothing that seemed to be related to that.
I'd appreciate any help with this.
