The [m.SO question][1] posted by Mark is from July of last year; in October of last year, a number of SO's "hidden features" questions were closed and locked - and even as recently as a week ago, the [one for Python][2] was (re)closed.

The majority of their "big" [hidden features questions][3] seem to be closed and/or locked, but some are not; it doesn't seem to be quite a settled debate.

But, hey: we're not Stack Overflow, and I think we can make this one idiosyncrasy that we choose not to inherit.
