Subject: regexp character classes and +

On page 71 of Pickaxe 2, discussing character classes, it says "The
significance of special regular expression characters (including +) is
turned off inside the brackets."

Why is this a valid regular expression (+ not the first character in
the character class)

%r{^[-+*/]$}

but this isn't? (+ is the first character in the character class)

%r{^[+-*/]$}
