So are the problems you listed not important for the decision or 
the answers are not convincing?

There is no “by default” in any non-managed language. If you are 
coming from C++ I’m really surprised to see this turn of phrase.

Speaking of defaults - Vibe.d is built on Fibers and has 
muliti-core mode that scales. It may have some issues on huge 
number of cores but it does work.

I take it Phoenix framework is “default” in Elixir? :)

I programmed in Go.
I also was part of Dart team for about a year.
So yeah, I know what you mean.

You can with C’s standard library. It’s all a matter of 
perspective and amount of stuff in std vs amount of your code on 
top.

IMHO what I see is that everybody goes on to invent a library 
that is somehow better than std lib one.
