Some time ago there have been a review for `std.signal` Phobos
It have not received much feedback and I was a it too busy to
proceed with final voting at that moment but with no outstanding
issues to address nothing prevents that final step.
Let's put 2 week deadline to refresh memories about the proposal
and make some decision. Voting closes at January 20th 23:59 GMT 0
Please take some time and help make Phobos better ;)
