Switching from PHP to Go is not a bad idea as CloudFlare have blazed
that trail and created a who community around it.

Sounds like some good people, using Go for good reasons not blind
fashion.

This is now a bit topic again in C++, witness all the debating over
constexpr and C++17 and C++20.

Clearly there are many feature similarities between D and Go as well as
differences (slices vs. generics). looked like a nice selection of
example in teh slides to pick up on this.

Thread pool and work stealing is clearly the way forward for
actor/dataflow architecture, though explicit threads have their place
as well.

std.parallelism has a task pool system. I wonder if there should be a
strategic move to (in some sense) merge std.concurrency, std.fibers and
std.parallelism into a single consistent whole (possibly remaining
three separate by connected packages rather than a single monolith.

Java has had great benefit from having a single concurrency/parallelism
strategy even though it ends up with different leaves not a monolith.
