To me the advantage of:

if ($y % 3 == 0) { }

[download]

is that you are explicitly stating that you are testing for a modulus being zero.

With:

unless ($y % 3) { }

[download]

you are saying you are interested in Perl's idea of the statement's truth/falsehood - which is a subtly different concept.
