I see that the code before uses version but I wouldn't overwrite the
version variable which normally points to the package's version. I
suggest guile-version or something similar.

Perhaps go-cache would be more descriptive
(I see that it was also 'go' before)

I'm not in love with this, I personally find it a bit hard to parse. I'm
not really sure what the (cdr input) is there for. (without testing it
myself) I'd suggest borrowing the filter-map code from guile-studio in
(gnu packages guile-xyz) where it searches for emacs packages.

(Again without really testing it) Perhaps it would be better to remove
this whole phase and to replace it with wrap-script.

Actually, forget all of that. There's a comment in (guix build utils)
saying that Guile scripts are not supported.
