struct vs. class, int vs. char.

[Denis Koroskin]

Here is another example:

import std.stdio;
import Scope;

class Foo
{
    this(int i, int j, int k) {
        writeln("Foo.this(): ", i, j, k);
    }
    
    ~this() {
        writeln("Foo.~this()");
    }
}

class Bar
{
    this(int i, int j, int k)
    {
        writeln("Bar.this(): ", i, j, k);
        foo = Scope!(Foo)(i, j, k);
    }
    
    ~this()
    {
        writeln("Bar.~this()");
    }

    Scope!(Foo) foo;
}

// Just for comparison - note that they are almost the same
class NoScopeBar
{
    this(int i, int j, int k)
    {
        writeln("NoScopeBar.this()");
        foo = new Foo(i, j, k);
    }

    ~this()
    {
        writeln("NoScopeBar.~this()");
    }

    Foo foo;
}

void main()
{
    auto bar = Scope!(Bar)(1, 2, 3);
}

Expected output:

Bar.this(): 123
Foo.this(): 123
Bar.~this()
Foo.~this()

Output:
Bar.this(): 123
Foo.this(): 123
Bar.~this()

It is a DMD bug: calling an object's dtor should call dtors on all its fields.
