Hi. I tried code below:

import std.concurrency;
import std.stdio;

void func()
{
    throw new Exception("I'm an exception");
}

void main()
{
    auto tID = spawn(&func);
    foreach(line; stdin.byLine)
        send(tID, "");
}

I expect my application will die immediatly, but main thread still
running and I don't see any errors.
I want to kill all my threads if it is unhandled exception.
How can I do that?

Hm... what about:

import std.traits: Parameters;

auto mySpawn(F)(F func, Parameters!F params)
{
    static auto callIt(F func, Parameters!F params)
    {
        try
        {
            return func(params);
        }
        catch(Throwable t)
        {
            // print the exception/error, e.g.:
            import std.writeln;
            writeln(e.toString());
            // terminate program
            import core.stdc.stdlib : exit;
            exit(1);
        }
    }

    return spawn(&callIt, func, params);
}

void main()
{
    auto tID = mySpawn(&func);
    ...
}
