Two bits for your thoughts

[Limbic~Region]

Monks,
This is not balladry, but it is artistic. If you crack my cryptic knot, I ask you not to ruin it.

Plural solutions apply!

if ( 'you monitor mindfully' ) {
    print "How quickly can you find out what is so unusual about this 
+script?\n"
}
if ( 'you look hard' ) {
    print "\n\nIt looks so ordinary that you would think that nothing 
+is wrong with it.\n"
}
if ( 'curiousity has you' ) {
    print "\n\nIn fact, nothing is wrong with it but it is unusual.  W
+hy?\n"
}
if ( 'your vision is not foggy' ) {
    print "\n\nIf you study it and think about it,",
          "\nyou may find out, but I am not going to assist you in any
+ way.\n"
}
if ( 'your brain is sharp' ) {
    print "\n\nYou must do it without coaching.\n",
          "No doubt, if you work at it for long, it will dawn on you.\
+n",
          "Who knows?\n",
          "Go to work and try your skill.\n",
          "Par is about half an hour.\n"
}

L~R

Hint: It works with warnings and with strict.

Additional Info: Randal has found all 3 solutions. A piddling of monks chatting too.
