They do not.

Not really, at least in practice. Many C++ developers do not use exceptions at all, with good reason.
>turing-complete language can generate arbitrary things and is not immune to halting problem, news at 11 :p
The point is that a relatively simple syntax error on behalf of the programmer generates an incomprehensible error message. This is just a comical example of that, and a lot of real world code using templates is full of opaque errors at the start. That said, concepts should help eventually.
