-## Range Types
-
-Range types that guarantee a value will always be within a given range also exist. Whenever possible, out-of-bounds values will fail at compile-time, otherwise they will fail at run-time.
-
-``` nimrod
-type
-  TwoDigits* = range[10..99]
-
-let a = 2
-var b: TwoDigits = 99 + a  # Fails at run-time
-let c: TwoDigits = 100  # Fails at compile-time
-```
-
-Also note that range types also work on any other ordinal type, so a range over an enum is also valid:
-
-``` nimrod
-type
-  MyEnum = enum
-    A, B, C, D, E
-  BToD = range[B..D]
-
-let value: BToD = C
-```
