Package: memo 1.1.2

memo: Hashmaps and Memoization (In-Memory Caching of Repeated Computations)

A simple in-memory, LRU cache that can be wrapped around any function to memoize it. The cache is keyed on a hash of the input data (using 'digest') or on pointer equivalence. Also includes a generic hashmap object that can key on any object type.
