How this code works? $" is the separator used when arrays are extrapolated in certain contexts (like in say "@array"), tie-ing it to 'main' means that it will be implemented in the scope of the main program. I'm not sure about bless\my$i and what ${$_[0]} is referring to when invoked in FETCH.
Give a man a fish and you feed him for a day. Give him a fishnet and you feed him for a lifetime. Ooops! Wait a minute! What if the fishnet brakes down? He will ask for an other fishnet or worse starve to death. Better yet to teach him how to make a fishnet. But what if he forgets how to make a fishnet? It is better to teach him where to look for knowledge on how to make a fishnet. But this can also go wrong. So ultimately it is best just telling him: 'Help yourself, stupid!'
