Maybe I am missing something.  To my knowledge, .go files produced by
Guile are not always reproducible, see bug#20272 [1].  And, from my
understanding, Guix cannot be reproducible until this bug had been
fixed.  Therefore, I am not convinced that this patch is worth under
this frame considering the build-time penalty it brings.

That’s said, maybe it’s better than nothing and the package ’guix’ is
barely built after all.  I do not know.

What people think?

Cheers,
simon
