Data.MaybeLike
Description
Defines MaybeLike typeclass - a generic way to look at some types as if they were Maybe
It is currently used to add maybe-ness to unboxed primitive types
in cases when it isn't possuble to just use `Maybe a` (e.g. unboxed arrays)
Synopsis
- class MaybeLike a v | a -> v where
Documentation
