The core devs' time will be saved by ignoring the sandbox (other than
their own features), and if it intrudes on them (eg, in the commit
notices), they will request that it forcibly be shut up. Cf. the
short exchange you had with Nick on the subject of commit notices.
ISTM that rather the goal is to ensure that features that would
otherwise be overlooked or be blocked because the proponent is
unwilling to follow through to the extent required (ie, by a new
proposal at the time of ending the moratorium) be given more
consideration. I don't think a sandbox will help with that, unless it
is designed to give incentives and help in producing *better*
proposals. Just collecting them in one place is not going to help.

It's a common pattern of discussion, for both stdlib and core
syntax/builtins, and I chose it because it was close to the boundary
of approval. I didn't want to choose nonstarters like multiline
blocks or trivial suggestions like a warning for "breakless for-else".

Are you sure you're not confusing it with the distutils thread(s)?

But those are precisely the people whose time you plan to save. The
only way to save their time is to do less reviewing. Having an
official sandbox might do that by giving the dross a place to collect,
so the core devs *never* look at it.<wink>

Yup. Precisely the kind of stuff that happens in real projects, not

Sure, but they generally also are core developers. I don't see why an
"official sandbox" will be of use to them.
