I don't see why we would need to use Switch to do some case conditionals and was wondering if anyone could shed some light why we have this feature.

To me, the following two codes are identical and are both as simple to make. It does the EXACT same thing and the syntax isn't so different, so why would we use switch instead of elsif? 

switch ($wday)
{
   case 0 { print "today is Sun"; }
   case 1 { print "today is Mon"; }
   case 2 { print "today is Tue"; }
   case 3 { print "today is Wed"; }
   case 4 { print "today is Thu"; }
   case 5 { print "today is Fri"; }
   case 6 { print "today is Sat"; }
}

   if   ($wday eq "0") { print "today is Sun"; }
   elsif($wday eq "1") { print "today is Mon"; }
   elsif($wday eq "2") { print "today is Tue"; }
   elsif($wday eq "3") { print "today is Wed"; }
   elsif($wday eq "4") { print "today is Thu"; }
   elsif($wday eq "5") { print "today is Fri"; }
   elsif($wday eq "6") { print "today is Sat"; }
