typed-digits

Provides a Digit type, with the base of the digit available as a type-level Nat. Thus, it can be guaranteed at compile-time that digits of different bases can't be added together.

Usage example

For more convenient provision of type-level parameters, it's recommended to use the DataKinds and TypeApplications extensions. Then, you can give type-level parameters using @, as seen below, instead of giving the full type.

>>> :set -XDataKinds -XTypeApplications
>>> import Data.TypedDigits
>>> let d = digit @9 3
>>> d
Just 3 (base 9)
