Pure Reason implementation of persistent immutable data structures.

Immutable-re provides a complete set of efficient persistent immutable data structures for Reason and OCaml, targeting both OCaml native and byte code compilation modes, as well JavaScript using BuckleScript.

The api includes concrete implementations of vectors, sets, and maps. Many implementations support transient mutability for efficient batch mutations. Additionally Immutable-re provides lazy functional iterators and sequences, along with type definitions for basic operators such as equality, comparison, and hashing.
