We can retitle it to remove the Guile banner indeed.

Err... I'm confused, this is not about Nyxt :p

If you tried with SBCL, then you need to first require UIOP:

--8<---------------cut here---------------start------------->8---
(require :uiop)
(with-input-from-string (s "(display \"foo\\n\")")
  (uiop:run-program '("guix" "repl") :input s :output :string :error-output 
nil))
--8<---------------cut here---------------end--------------->8---

Oops, thanks for the reminder.  Will do indeed, I don't think it's
needed in Nyxt.  Or maybe make it optional.  Well, if someone ever
complains about it...

Cheers!
