Here is a reduced test case, that I wish I had before I
tried to make 1000 lines of code work with immutable:

struct B {
    ~this() { /* some cleanup */ }
}

struct C {
    immutable B b;
}

void main() {
    C(immutable B());
}

That's pretty much it. You cannot use compose a mutable struct
out of immutable ones with dtors.
