Interpolation occurs between double quotes or qq

Please read perlop carefully, particularly the Quote-Like Operators section where it says: 

    q/STRING/
    'STRING'
        A single-quoted, literal string.  A backslash represents a backslash unless followed by the
        delimiter or another backslash, in which case the delimiter or backslash is interpolated.
