To make example real simple:
struct D{
int x;
~this()
{
}
}
void foo(D bar)
{
(){ bar.x++; }();
}
void main()
{
foo(D.init);
}
Note that even though there is no need for allocating closure at all.
Compiler should deal with such cases by tiying the lifetime of dtor-able
variables to that of a closure if one is indeed required.
This is critical as std.array.array and other functions started using internal
lambdas for trusted blocks making use of any RefCounted range impossible.
