Perl also provides quite a few functions that operate on arrays. As you learn more and more Perl, you will see lots of interesting functions that work with arrays.

push, pop, shift, and unshift.
The names shift and unshift are an artifact of the
Unix shells that used them to "shift around" incoming arguments.
