I am unable to define a destructor in a struct which may or may not be shared. Possible duplicate of issue #12004, because if Macro's suggestion were followed, it would solve the problem for my use case.

struct Foo
{
	~this () {}
}
struct Bar
{
	shared ~this () {}
}
struct Baz
{
	~this () {}
	shared ~this () {} // source/main.d(44): Error: destructor main.Baz.~this conflicts with destructor main.Baz.~this at source/main.d(43)
}
void main ()
{
	Foo foo;
	shared Bar bar;

	shared Foo s_foo; // source/main.d(51): Error: non-shared method main.Foo.~this is not callable using a shared object
	Bar n_bar; // source/main.d(52): Error: shared method main.Bar.~this is not callable using a non-shared object
}
