;; The use of dynamic-require throughout this file is intentional:

;; this way, low-dependency raco commands (like "version") are faster.

;; Whereas with `require` or `local-require`, everything would have to be front-loaded.
|
|
;; but ... maybe most of the latency is due to pollen/world environment checking.
