After reading from the Perl Blackbook I don't see any difference between these regex assertions. Can someone explain them?

The difference between ^ which matches the beginning of a string and \A which matches at the beginning of the string.

The difference between $ which matches the end of a string and \Z and \z which match the end of the string.

The explanations seem to make these sound like they're identical, but there must be a difference, right?
