Yea that's where the `scanTuple` came from originally it did automatically 
declare the variables, but Araq prefered the tuple method, so it's what we get, 
it's equally as good. 
    
    
    let (success, field, min1, max1, min1, max1) = line.scanTuple("$+: $i-$i or 
$i-$i")
    if success:
       echo field, " is", [min1..max1, min2..max2]
    
    
    Run
