Revered monks,
I am curious about the syntax of the switch module. I have seen two variations and both seem to work. I wanted to know which of these 2 is the correct one.
I am also curious to know why both of them work!! Isn't semicolon a requirement??!
use Switch;
switch ($char)
{
case 1 { print "1" }
case 2 { print "2" }
}
Note: The semicolons are missing above and are present below
use Switch;
switch ($char)
{
case 1 { print "1"; }
case 2 { print "2"; }
}
Any light on this behaviour of Perl is greatly appreciated.
Thanks
