Zict: Composable Mutable Mappings

Zict provides a collection of abstract MutableMapping classes that can be composed to build complex storage systems. It allows developers to create custom dictionaries that manage data across different locations (in-memory, on disk), apply various eviction policies (like LRU), and handle data transformations (compression, serialization). This enables intuitive interfaces over sophisticated storage strategies. The library is currently at version 3.0.0 and appears to be actively maintained.
