+;;; Commentary:
+
+;; This file should define all global configurable variables which
+;; doesn't belong anywhere else. The config module should then import
+;; this module, and set all configs as needed. The config module
+;; should also be able to set configs gotten from other parts.

+(define (ensure pred?)

+    (unless (pred? v)
+      (error "Bad value to config"))
