Nice example that speaks by itself:

=================
int i;
struct Foo
{
     template ToMix(){ ~this(){++++i;}}
     ~this(){++i;}
     mixin ToMix;
}

void main()
{
     Foo* foo = new Foo;
     foo.__xdtor;
     assert(i==3);
     Foo* other = new Foo;
     foo.__dtor;
     assert(i==4); // and not 6 ;)
}
