newtype Offset ty

Offset in a data structure consisting of elements of type ty.

Int is a terrible backing type which is hard to get away from, considering that GHC/Haskell are mostly using this for offset. Trying to bring some sanity by a lightweight wrapping.

newtype CountOf ty

CountOf of a data structure.

More specifically, it represents the number of elements of type ty that fit into the data structure.

>>> length (fromList ['a', 'b', 'c', '🌟']) :: CountOf Char
CountOf 4

Same caveats as Offset apply here.
