in thread What does _ mean?

Based on merlyn's response below there is virtually no reason to use the underscore anymore.

Except 

if ( -r -w -e -f  $file and -s _ > 2300 ){
    print "found a candidate\n";
}

    This thread has been about whether avoinding a second call to stat for a trivial performance gain is worth it or if it's better to use $file twice so that people reading the code do not have to try and figure out what the obscure "_" feature does. Unless using "_" in this context results in some other behavior beyond saving a call to stat you have contributed nothing new to this discussion/debate!!
