In Guile, if you start a REPL, the REPL is inside some module.  By
default, this module is the (guile-user) module (or (guix-user), when
using "guix repl"), although this can be changed with ',m' and maybe by
stepping through the debugger (not sure).

As such, if you run (define foo 'bar) inside a REPL currently in
(guile-user), then this corresponds to defining a top-level
variable/module variable inside the (guile-user) module.

Summarised: REPL environments have a corresponding Guile module and in
Guile, there is no meaningful distinction between "top-level variable"
and "module variable", unlike in Racket.

Greetings,
Maxime.
