@name means the array "name". Perl isn't sure whether or not you want to expand the array for use in the RE, so you need to escape it so that perl has no question about what you're trying to do. By default, the array is expanded. This is the same reason you need to escape dollar signs, since $name is the scalar variable "name". ie: $ perl -e '@t=(1,2,3); $t=qr/@t/; print "$t\n"' (?-xism:1 2 3) versus $ perl -e '@t=(1,2,3); $t=qr/[EMAIL PROTECTED]/; print "$t\n"' (?-xism:[EMAIL PROTECTED]) :) -- Randomly Generated Tagline: "I don't get it.
