Suppose you made a tool for your STL that throws compile-time errors when trying to copy references, so your pointers remain tidy.
Suppose also that the language has a a turing-complete preprocessor that can be used to throw useful errors.
Then WHY THE FUCK DOES UNIQUE_PTR NOT OVERRIDE THE DEFAULT ERRORS WHICH TELL ME NOTHING ABOUT WHAT I FUCKED UP BUT PRETEND UNIQUE_PTR IS AT FAULT FOR NOT DEFINING "OPERATOR=" ?
