Thank you everybody - Especially for the links to the blogs. This
is just the kind of stuff I seek (didn't give a close look yet,
though).
I think I'm going to try std.socket first, since it's in the
standard library. If it feels like it could be easier, I'll
consider Libasync.

Naive newbie question:
Can we have (in theory) in D lang memory management like V lang?
I don't know V so can't be sure, but doing it the same way as in
the examples sounds possible.
The first two calls are easy. D string literals
I have a Vibe.D server binary that, locally at least, works. But
only without TLS. I want to add TLS to it and test it locally
with a self-signed certificate. I made one with LibreSSL, stored
in `cert.crt` and `key.key`. The application main function:

Is there a good way to simulate computed goto in D?
I haven't used assembly myself, but it's possible that you can
define a mixin that does this, using inline assembly.

So to simulate computed goto have to
1. wrap switch(x) in a loop [ while(0) ]

3. jump back to execute switch again [ continue ]
It does look as if a nested switch can co

Allocate a `shared int` before the foreach loop. In the loop

In the sayHello function, you are converting a pointer to utf16
character into utf8 string, not utf16 string to utf8 string.
Convert the C wstring to a D `wstring` first
