The final issue we have yet to address with double-quoted strings is the use of `$' and `@'. These two characters must always be quoted. The reason for this is not apparent now, but be sure to keep this rule in mind until we learn why this is needed. For now, it is enough to remember that in double-quoted strings, Perl does something special with `$' and `@', and thus we must be careful to quote them. (If you cannot wait to find out why, you should read Scalar Interpolation and Array Interpolation.
