+// 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.
