Destruction Sequence: module and classes defined within

[vano]

The code below:
    module used;

    import std.stdio;
    class ClassA {
        this()  { writeln("A ctor"); }
        ~this() { writeln("A dtor"); }
    }

    static this()  { writeln("used.sctor"); }
    static ~this() { writeln("used.sdtor"); }

    void main() {
        auto a = new ClassA();
    }
produces the following output (DMD v2.049):
    used.sctor
    A ctor
    used.sdtor
    A dtor

The question is: should the module be allowed to be unloaded before all 
module-level objects/structures are destructed/unloaded?
