import core.stdc.stdio;

void main()

    printf("Hello World, what's happening");
}

Well, since I had a deep dive in the Windows world...

extern(Windows) void GetStdHandle(int);
extern(Windows) void WriteFile(size_t, size_t, int, size_t, size_t);
extern(Windows) void ExitProcess(int);

int main()
{
   asm
   {
        naked;
        push -11;
        call GetStdHandle;
        mov EBX, EAX;
        push 0;
        lea EAX, [ESP - 4];
        push EAX;
        push 11;
        push msg;
        push EBX;
        call WriteFile;
        push 0;
        call ExitProcess;
   msg:
        db "Hello Pedro\n";
   }
}

import std;

void main()
{
    throw new Exception("Goodbye cruel world!");
}

Oops was meant to be

void main()
{
    throw new Exception("Goodbye cruel world!");
}
