I see a lot of code that usrs:
my $i = 0;
Why do so many people use $i ? It is a special variable in PERL maybe for
integers?
It has no special significance. Many people use it to refer to the
*I*ndex of a list or array.
People have been using $i as a counter variable for a couple decades at
least.
