Strict linked lists for Haskell, with stack-safe operations and reversed-order helpers for efficient intermediate work.

Example

{-# LANGUAGE OverloadedLists #-}

import StrictList

numbers :: StrictList Int
numbers = [1, 2, 3]

The strict list type was renamed from List to StrictList throughout the API to avoid confusion with the List type alias from base.
Ord for StrictList now matches the standard lazy list ordering, so empty lists compare smaller than non-empty lists and lexicographic comparison follows the usual [] semantics.
