Here an example:
--8<---------------cut here---------------start------------->8---
(define (assoc-args-ref pkg key)
"Return the value associated with KEY in the arguments of package PKG,
or #F if there is no such key."
(let ((ref (find-tail (cut eq? <> key)
(package-arguments pkg))))
(and=> ref second)))
(assoc-args-ref golang-github-com-audriusbutkevicius-go-nat-pmp
#:import-path)
=> "github.com/AudriusButkevicius/go-nat-pmp"
--8<---------------cut here---------------end--------------->8---
