+// TODO(3449): Yield bare primitives in var replacements from configmaps.
+// The ConfigMap data field is always strings, and anything that looks
+// like a boolean or int or float must be quoted, or the API server won't
+// accept the map.  This creates a problem if one wants to use a var to
+// inject a raw number or raw boolean sourced from a configmap, because as
+// far as the configmap representation is concerned, it's a string.
+// A workaround would be to source the var from another Kind, from a field
+// that allowed unquoted vars or booleans.
