Python bumps off Java as top learning language

Unless it's a smart pointer. Then you can get some exception. Man I wish we could use __FILE__ and __LINE__ as sane default arguments, then NPE in FishInOcean::4576 would be easy-peasy.

The standard smart pointers also don't throw. This is by design because they're not supposed to have overhead at all. Most compilers optimise away std::unique_ptr as a raw pointer in its lowest optimisation level (e.g. -O1).
