Agreed. But that in turn implies to me that __preview__.foo should not be maintained as an alias for foo once it gets "promoted". Firstly, because if you're not comfortable with changing your code to make the simple change to remove the __preview__ prefix in the import, then how could you be comfortable with using a module with no compatibility guarantee anyway? (BTW, I assume that the normal incantation would actually be "from __preview__ import foo", as that limits the module name change to the import statement). > The idea that being on PyPI is sufficient is nice but flawed (the > IPaddr example).

We need a way to signal somehow that a module is being seriously considered for stdlib inclusion. That *would* result in more uptake, and hence more testing and feedback. As an example, I would definitely try out MRAB's regex module if it were in __preview__, but even though I keep meaning to, I've never actually got round to bothering to download from PyPI - I end up just using the stdlib re for my one-off scripts. > On the other hand, __preview__ would clearly signal that something is > on the verge of being frozen as an official stdlib API, and would > prompt people to actively try it. Precisely. It's in effect a "last call for feedback", and people should view it that way, in my opinion.
