People saying this: we KNOW this approach doesn't work in all cases. If it worked perfectly, regex would be in the standard library by now. Don't consider this PEP a purely theoretical proposal, because it isn't. It's really being put forward to solve a specific problem: the fact that we need to do something about re's lack of proper Unicode support [1]. Those issues are actually hard to solve, so replacing re with Matthew Barnett's regex module (just as re itself was a replacement for the original regex module) that already addresses most of them seems like a good way forward, but this is currently being blocked because there are still a few lingering concerns with maintainability and backwards compatibility. We *need* to break the impasse preventing its inclusion in the standard library, and __preview__ lets us do that without running roughshod over the legitimate core developer concerns raised in the associated tracker issue [2]. With the current criteria for stdlib inclusion, it doesn't *matter* if a module is oh-so-close to being accepted: it gets rejected anyway, just like a module that has no chance of ever being suitable. There is currently *no* path forward for resolving any stdlib-specific concerns that arise with already popular PyPI modules, and so such situations remain unresolved and key components of the standard library stagnate. While regex is the current poster-child for this problem, it's quite likely that similar problems will arise in the future. Kenneth Reitz's requests module is an obvious candidate: it's enormously popular with users, Kenneth has indicated he's amenable to the idea of stdlib inclusion once the feature set is sufficiently stable (i.e. not for 3.3), but I expect there will be legitimate concerns with incorporating it, given its scope. Cheers, Nick.
