Presbyterian. Well no, but see http://google-styleguide.googlecode.com/svn/trunk/cppguide.x... for some rationale in that direction. Generally speaking you might note that in Java and C#, if you want to copy a data structure, you have to do so explicitly.

Yeah I agree that one should intentionally enable or disable copy and assignment for a type. It might even make sense to disable implicit copying and make an explicit method for it instead.

The C++11 move constructor and move assignment operator seem to me to be a wonderful middle ground.
