I don't think there are special meanings for "@a" and "@b", I think you may be thinking about "$a" and "$b" which are identified as special variable for use in perl sort, see perlvar. perlcritic will create a message "Magic variable "@a" should be assigned as "local" at line..."; however, I am not aware of and cannot find any reference to "@a" or "@b" as being a magic variable

Please explain if I am missing something!

Cheers, lbe
