;;   `(math.Sqrt x)`    - Go-style; calls Go's stdlib `math.Sqrt`
;;                        directly. Case matters: Go names are
;;                        capitalised.
;;
;; For `sqrt` the two paths happen to produce identical output. The
;; difference shows up in the cases from 04-jvm-semantics: Go's stdlib
;; will not give you JVM-faithful `floorDiv` or `round(-2.5)`.
