If you use a user-defined type `FooType` in an assertion, you must make sure

there is an `std::ostream& operator<<(std::ostream&, const FooType&)` function

defined such that we can print a value of `FooType`.

In addition, if `FooType` is declared in a name space, the `<<` operator also

needs to be defined in the *same* name space. See abseil.io/tips/49 for details.
