Yes - enough guessing - I'll do my best to do some counting with different libraries (both for DOM and for nodejs) and report back some numbers. Erg - busy work : ) Any one else want to help? We should be able to get a good idea by counting anonymous function expressions, and of those, which ones only contain a single statement, which is a return statement. kevin
