/*! Useful in metaprogramming to give errors where a static_assert isn't appropriate. For example, we need a class
46
that indicates whether a type is an EvenCoolerClass or not, and typedef it if it is. What should we do if it isn't
47
though? We want to let people know that they are accessing something that could be, but isn't defined.
