The code from comment 3 still fails. Moved to new issue 18746.

I'm not really happy with it, but I don't know a better way to write it.

Very similar case:


struct S {}

S f(ref int i)
{
++i;
return S();
}

void main()
{
int i = 2;
assert(f(i) == S());
assert(i == 3); // fails, i = 2
}


With the enum, the struct doesn't have to be empty, but here it does.

I guess this is valid.  It works correctly when a is a static var or a static
function.
