Although I should have known about it long ago, I have only just become
aware of Andrei's std.benchmark, which appears in his fork of Phobos,
but not in real Phobos. Is there an intention it should be in Phobos, or
is it intended to be a separate thing?
For me a benchmark framework should be outputting means, standard
deviations, and degrees of freedom of the timing of the function under
test. However the documentation comments of the std.benchmark module in
Andrei's repository only talk about a time and a relationship between a
group of related tests. So for me what is there is a great start but not
enough to be really useful.
Is anyone working on this? Is there an intention to make this part of
Phobos?
Hopefully I am not blundering into a quagmire raising this.

A google search turns up a long review thread a couple years ago:

Looks like it was remanded for further fixes, it shows as a "work

Given there has been no activity in over 2 years, I guess it is deemed a
dead duck in it's current form/place.
Instead of wallowing in the backwaters of non-Phobosity, it should
become a module accessible independently via a DVCS (presumably Git),
and Dub? (though I will be using SCons) such that people can amend,
extend and send in pull requests.

If i am not mistaken, parts of std.benchmark moved into
std.datetime. After this work on std.benchmark stopped.

I'd love to see Andrei comment about it to either update its
status or remove from review queue.

I will work on it but std.allocator takes precedence. If anyone is in a
hurry, please take it over. I think std.benchmark can and will be
awesome. -- Andrei

Seconded. std.allocator takes precedence, but a std.benchmark
with proper statistics built-in will be awesome.

It was a solid review cycle that prompted good things to fix and
improve. std.benchmark will be part of std iff we make it so. -- Andrei

Clearly the data about the things is in the email thread, but might it
be worth creating a summary document so there is a definitive "todo
list"?
There is then also the issue of:
1. Completing the todo list for a new review for entry into Phobos;
versus
2. Extending the framework to handle multiple runs, and statistics on
the dataset.
Should these be seen as in competition (so that all work on 2 should
happen in a separate branch to that on 1), or whether 2 should be seen
as contributing to 1.
No problems with either direction, but it is probably a good idea to
take a view on this early.

On the grounds of "do, don't just talk", I have created
https://github.com/russel/D_Benchmark initialized with a copy of
https://github.com/andralex/phobos/blob/benchmark/std/benchmark.d.
Anyone interested in evolving this, please feel free to clone and send
in pull requests.

moving<br/>
into std.benchmark (which is arguably a better place for them). And I
expect<br/>
that they well be moved into std.benchmark at some point in the future, but<br/>
std.benchmark ran into some difficult technical problems that have yet to

I talked with Andrei brielfy about it at dconf (because I want to move
