Try using the LDC2 compiler, with the ctRegex, and using the

If that fails one solution is to write your own finite state

For example, __dtor may not be the full destructor, but just the code
represented by ~this(). I think this is the case for structs.

As a guide, you should take a look at the destroy function in
