This module inspired by Flask, threading.local and werkzeug.local local object implementation.
See code:

http://werkzeug.pocoo.org/docs/0.12/local
The module provides local context object with manager and proxy helpers. Local context object is a special object which defines globally providing ability to thread-safe access and manipulation with it attributes. CRUD operation set guarantied :)
E.g. you can use one generally global object with attribute values would be local and separated to each thread without any interference.
