Here is a simple deep-copying smart pointer.

I just wrote it as an example.

...it looks like you are using placement new

I wrote this quite late, and mixed things up because initially I felt like writing things based on an allocator, but decided not to make things too complex. Obviously it should have been regular new, and not placement new.

Why? I mean since when is the CV qualification of a pointer relevant for the CV qualification of the pointee?

I thought it was relevant for private implementations. If the object is const, the implementation details should be const too.
