+;; TODO: Consider how vars might be used in task args Currently a task argument
+;; can be a context refrence, for example we could write:
+;;
+;;  (install-directory (context-ref 'base-dir))
+;;
+;; but there's no way to nest these, so we this will not work:
+;;
+;; (install-file (file-name-join (context-ref 'base-dir) "foo"))
+;;
+;; Maybe we could implement something like:
+;;
+;; (install-file (context-fn (file-name-join (context-ref 'base-dir) "foo")))
+;;
+;; where context-fn is some syntax that returns (lambda (ctx) ...)
