Exactly.  From page 15 of the "perlre" man page:
 
You can specify a character class, by enclosing a list of characters
in [], which will match any one character from the list.  If the first
character after the "[" is "^", the class matches any character not in
the list.  Within a list, the "-" character is used to specify a
range, so that a-z represents all characters between "a" and "z",
inclusive.  If you want "-" itself to be a member of a class, put it
at the start or end of the list, or escape it with a backslash.
