Somehow, it feels good to use it and after a while you find yourself reveling in complexity. I'm almost ashamed to say really.
R-value references, for example. This is entirely a problem that C++ has created for itself with its copy semantics. From inside the C++ ecosystem, the language feature makes sense, but from outside the C++ ecosystem, the idea that there are now two types of references and two types of copy semantics triggered based on the implicit interaction of reference types, and you sometimes need to do idiomatic things like declaring undefined private copy constructors to lock down unintended implicit behaviors relating to copy semantics for R-value references... yup, hamster wheel.
C++ isn't the only language where I get this feeling. I think Scala is pretty guilty of this too. It's not that I can't grok it if I wanted to (survived my share of proof based, pure theory math classes back in college), it's that I think it's entirely too much energy to be spending on mundane code.
include normal pointers and it's three.
