Hi Everyone,
I am proposing a new PEP, still in draft form, to impose a limit of
one
million on various aspects of Python programs, such as the lines of code per module.
Any thoughts or feedback?

Overall I /like/ the idea of limits... /But.../ in my experience, limits like this tend to impact generated source code or generated bytecode, and thus any program that transitively uses those.
Hard limits within the Javaish world have been *a major pain* on the Android platform for example. I wouldn't call workarounds straightforward when it comes to total number of classes or methods in a process.
Do you have any numbers? 1M is a lot bigger then 64K, but real world numbers would be helpful.
I guess the relevant case in question is with Facebook patching the limit of 65,000 classes in Android : https://m.facebook.com/notes/facebook-engineering/under-the-hood-dalvik-patc...
If we're to adopt limits where there were previously none, we need to do it via a multi-release deprecation cycle feedback loop to give people a way to find report use cases that exceed the limits in real world practical applications. So the limits can be reconsidered or the recommended workarounds tested and agreed upon.
