I think we should make a semi-private (public to the stdlib) module like sys or implementation part of the Python VM API. Then, instead of stuffing everything into sys, we can provide this information in modules where it belongs.

That's an interesting counter proposal. Your idea requires an additional import that I try to avoid. Looking at memory and performance, an additional module that is imported anyway isn't better. In my humble opinion the implementation information belongs into the sys module anyway. A new module just for the user site suffix seems unnecessary.

But we want to hide that this is an implementation detail from the user. Having a new module just for this attribute might seem like overkill, but I hope that we could use it for more things in the future. Besides, if _sys is a builtin module, importing it will not add much overhead.

I forgot to ask before: Does this deprecate platform.python_implementation()?
