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