I'm worring about performance much.

Dict has ma_version from Python 3.6 to be used for future optimization including global caching. Adding more abstraction layer may make it difficult.

Can we make it opt-in, by replacing the module __dict__ when and only if needed? Perhaps we could replace it on the fly with a dict subclass that defines __missing__? That's virtually the same as __getattr__. Then modules which haven't replaced their __dict__ would not see any slow down at all. Does any of this make sense, or am I talking nonsense on stilts? -- Steve
