in reply to what is...

Ah, the whimsy of programmers. Various combinations of "foo", "bar", "baz" and other strings involving seemingly random chracters have been used as arbitrary variable identifiers when the programmer can't be bothered to think of one since time began. The technical term is "metasyntactic variables". They're not special to Perl. :)

For more info, see metasyntactic variables at FOLDOC.
