I'm still having hard time understanding what's the difference between contains and the good old indexOf beside the RegExp check ... but I agree having multiple explicit searches instead of multiple implicit searches won't make such big difference. Good news is, you probably will still use RegExp anyway because names can be composed and haveing a \bName\b helper is probably what you might need anyway :-)
