Hi!

Oh, good catch!

Above the =E2=80=98wrap-program=E2=80=99 call, there=E2=80=99s this comment:

        ;; Ignore user settings so that a bogus
        ;; GUILE_LOAD_COMPILED_PATH does not prevent use of
        ;; 'guix', notably when it contains entries pointing to
        ;; incompatible .go files as reported at
        ;; <https://lists.gnu.org/archive/html/guix-devel/2016-03/msg01261.=
html>.

Since 2.0.12, Guile skips invalid .go files, so this problem is gone.
So I think you can go ahead and change '=3D to 'prefix there.

Thanks!
