But I honestly don't see why this doesn't belong in sys; it has to do with the system environment which is the interpreter. Yes, some things currently in sys could possibly be put elsewhere (e.g. the exception stuff could be in 'exceptions'), but I don't think sys is that much of an odd collection of code. Without having a desire to eventually clean up the sys module (which I am not proposing as I know that will never fly) I don't see this as being worth it.

That doesn't mean we have to make it more dirty. usersiteprefix is used exclusively by site.py to load user modules; it has no function in the interpreter core.

Besides, if sys is a builtin module, importing it will not add much overhead. Well, that's assuming the other interpreters makes it built-in. Otherwise it's only a CPython/python.org perk.

As far as I am aware, all current Python implementations can build in modules.
