I learned that allocation in a destructor isn't the only crash
case here.
The GC calls a class instance's invariant() method during a
collection cycle, before calling the object's destructor, and
possibly after destructing objects it references. So if the
invariant() touches any of its member references, it can crash!
A solution to that would be to never call invariants during a
collection cycle, but what other gotcha's exist during
collection? Would @nogc on class destructors help them?
