As an aside, the same applies to the common warning against using the global values $a and $b 'because they are used by sort'. Once again, sort localizes these variables within the comparison code so there is very little chance of inadvertently modifying their values.
The warning about $a and $b is not because Perl will get confused, it's because the people reading it will. And unless it's part of a well-known mathematical formula, one shouldn't use single-letter variables. Use a more meaningful name instead.
