Speaking only for myself, but really for anybody who likes tidy source directories, I hope some version of the __pycache__ proposal becomes part of standard Python, by which I ideally mean it's enabled by default but if that is just not a good idea then at most it should be required to set a command-line option to get this feature.

This doesn't contradict by my proposal.

What I am proposing is that the creation of __pycache__ /directories/ be put
outside of the core. It can be part of distutils, or of a separate module, or
delegated to third-party tools. It could even be as simple as
"python -m compileall --pycache", if someone implements it.

Creation of the __pycache__ /contents/ (files inside the directory) would still
be part of core Python, but only if the directory exists and is writable by the
current process.

If I understand correctly, we would have the current mode as the default, and can trigger __pycache__ behavior simply by manually creating a __pycache__ directory and deleting any byte-code files in the module/program directory.

I like this, it is easy to understand and can be used without messing with flags or environment variables.
