Here I have a program that wants to
1. detect whether if it's the only instance
1.1. it does that by trying to create a Unix Domain Socket
and trying to binding it to a specific address.
2. if a duplicate program is not running, establish an UDS
and then listen to the socket.

In C# you can do something like:
if (obj is Person)
{
var person = obj as Person;
// do stuff with person...
}
where you can check the type of an object prior to casting. Does
D have a similar mechanism? It's so widely useful in the C# realm
that they even added

better composition over inheritance. So I do something like:

Looks the same as D's
if(auto person = cast(Person) obj) {
// use person in here
} else {
// it was some other type
}
Even though static solutions would be more performance minded,
I'd actually prefer to see the runtime equivalent so I don't have
to rethink how I think as performance isn't really my major
concern right now.

Missing _getmaxstdio / _setmaxstdio?
I'd like to try and increase the limit of open files without
resorting to Windows API, is it possible or will I have to resort
to the WinAPI to achieve this?

I have started working with neural networks and for that I need a
lot of computing power but the programs I make only use around
30% of the cpu, or at least that is what Task Manager tells me.
How can I make it use all 4 cores of my AMD FX-4300 and how can I
make it use 100% of it?

Hello,

This is my first dlang work:

You should use fromStringZ:
I have two project I want to compile and both times get this error:
Undefined symbols for architecture x86_64:
"_dyld_enumerate_tlv_storage", referenced from:
__d_dyld_getTLSRange in libphobos2.a(osx_tls.o)
I'm wondering where this comes from as I didn't see it in the past. Any idea?

They are the same functions, so the idea is you can just use
