Thank you! Something must be up with either the Guile REPL or the Guile REPL inside Emacs' M-x shell. I tried to run socket in it and it could not find that. I also ran other code before that, so maybe the issue was, that that somehow prevented the REPL from finding the bindings. However, now that I tried what you wrote in a completely new REPL in a XFCE terminal, it works flawlessly. And such a thing has happened to me before with another module inside Emacs M-x shell mode. I think what I can take from this is, that if there is no use-modules part in the docs, it is likely available without running such and if it is not available I should check outside of Emacs in a standard terminal emulator.
