In node How can I tell if a variable is tainted? the docu says there is no -w clean way to detect taintedness. However when I tried 
sub taintedness {
!eval {
  eval substr(join("",@_),0,0)."1"
 }
}

no -w warning popped up. Does this mean this way to test for taintedness is unreliable? Or should there be a warning, that was somehow forgotten?
