Jenda is correct. I like to think of '=>' as "The FANCY comma!!".
It's just a pretty way of typing a comma for just such an occasion
when you want you code to reflect what you're doing. So, in the
above, I'm sending a signal to $pid, so the big arrow "shows" that the
signal (0) is being sent to that process ($pid)! Perl is Fun!!!
This works great (and is seen most often) in hash declarations:
my %demo_hash = (
Key_One => 1,
Key_Two => 2,
Key_Three => 3
);
