In function top-repl, at /usr/share/guile/1.6/ice-9/boot-9.scm:3022:

    (if (provided? 'regex)
        (module-use! guile-user-module (resolve-interface '(ice-9 regex))))

This function is set up for a call in script.c if a -c or -s option is
not used.

top-repl makes this and other modifications to the environment (other
module loadings, signal handlers, etc) before, well, starting the REPL.
