Cool stuff. 
I can definitely see use for catch-all-in-certain-range, opposite of filling 
every gap with their specifics, which is maintenance heavy. This matches the 
val_to_string() default string used when no match is found, but then in a 
higher dimension. I would say let the ranges decide, if their union is the same 
as the catch-all then it’s okay, otherwise mark it.
