I would guess not, but I wouldn't bet on it. ;)
And thanks a lot for your input, Arthur.

Yup, I have to agree. Use cases drive library adoption. Linear algebra started with an assessment of what's already happening in that space.

I wonder if there is a ring buffer "concept" waiting to be described...?

(joke)

Cheers,

Thanks very much Ben, Staffan. Just a small clarification for ring buffer update:
Inbal: Technical difficulties with ring buffer meeting yesterday.  Gathering the various inputs for the ring buffer. One option is to propose some ring buffer (P0059) abilities to P1958 and P0260. Use cases are welcome, so that we can decide if expanding P1958 is worthwhile. Jens suggested a use case for a ring span, I have formed an initial API and hoping to have his feedback on it.

My experience from P0059 is that anything we do for "ring buffer" should start from use cases, by which I mean sample code collected from the wild

- People are remarkably awful at describing their use-cases in English.
- People are remarkably awful at estimating whether a given API will work for their use-case.

IMO the only thing that works is "Committee-aided refactoring": look at how their actual code is actually physically written today, and then show how it could be rewritten in terms of a proposed new API while still accomplishing the same job.

If this project stalls for lack of real-world code samples, then maybe the problem isn't such an important one after all. (That was the impression I was left with after P0059.) Or rather, maybe there is no "the" problem; maybe there are many different use-cases with incompatible requirements (generic, thread-safe, non-owning, fast, MPMC, SPSC,...) and also different usage patterns (so there's not even any point in trying to define a "concept" or "interface" that all instantiations might satisfy).

my $.02,
