Well, yes, that is a quick and easy question. I don't think there is a quick and easy answer because that depends on what you actually want to know and you've not given enough context for us to tell. Here are a couple of answers to get you started:

It is a scalar variable which may be used to store a number or a string or a reference to something
In a context like this for (my $i = 0; $i < $limit; ++$i) is is a counter or, more likely, an index in a C'ish for loop. There are probably better ways to do this.

Perl is Huffman encoded by design.
