Why do you think that? No, you don't have to write a constructor,
destructor, or an assigment operator for the pimpl_ptr to work. Please
look at the example/default.cpp file.

Again, I don't know why you think this it true - unless I'm missing
something. When constructed/destructed the T type isn't undefined since
it's defined in the cpp file. That's the fact I've build this library on

Still I don't agree with you. Do you have an example to showcase this?
