Dpaste seems not working, so, sorry for code

----lib.d---
import std.stdio;

static this()
{
	writeln("module ctor");
}

static ~this()
{
	writeln("module dtor");
}

class A
{
	private string text;;
	this(string text)
	{
		writeln("class ctor");
		this.text = text;
	}
	void tell()
	{
		writeln(this.text);
	}
	~this()
	{
		writeln(this.text);
		writeln("dtor");
	}
	static this()
	{
		writeln("static ctor");
	}
	static ~this()
	{
		writeln("static dtor");
	}
}

-----main.d----
import lib;

void main()
{
	auto a = new A("some text");
	a.tell();
}
