It is better to replace the function name with %s.

I am just wondering:
Can you also make that refactoring change for the panic() call as well?
How about checking the whole file for such patterns and doing that
change for all occurrences?

Yeah, that would be ideal if gumingtao is willing to do it. These are
some instances where the function name actually mismatches. gumingtao,
would you be willing to do this?
