// ABSL_PRETTY_FUNCTION
//
// In C++11, __func__ gives the undecorated name of the current function.  That
// is, "main", not "int main()".  Various compilers give extra macros to get the
// decorated function name, including return type and arguments, to
// differentiate between overload sets.  ABSL_PRETTY_FUNCTION is a portable
// version of these macros which forwards to the correct macro on each compiler.
