Design Pattern
Lazy instantiation (aka lazy initialisation) in Python and the Webel Cascading Lazy Pattern
CAVEAT: This guide needs some more supporting code examples. For now, this description in text and graphs do already describe the pattern quite well.
Terminology:

Contexts and Dependency Injection (CDI) zone
Based on decades of experience with Design Patterns and Enterprise Java web applications - and other types of Java applications too - Contexts and Dependency Injection (CDI) is a thing of architectural beauty and wonder!
