Hash-based, immutable collection types for PureScript.
The two main goals are good performance and API compatibility with the
Ord-based collections wherever reasonable.
The implementation of
HashMap is based on "Optimizing Hash-Array
Mapped Tries for Fast and Lean Immutable JVM Collections" (Steindorfer
and Vinju, OOPSLA 2015, https://doi.org/10.1145/2814270.2814312).
HashMaps are fast. Most common operations are 1.5x-3x faster than the
Ord-based map. Very limited testing puts
around 10% faster than immutable.js.
