    # Given a selector array which is a list of strings with Sass::Script::Nodes
    # interspersed within them, return an array of strings representing those
    # selectors with the Sass::Script::Nodes removed (i.e., ignoring
    # interpolation). For example:
    #
    # .selector-one, .selector-#{$var}-two
    #
    # becomes:
    #
    # .selector-one, .selector--two
    #
    # This is useful for lints that wish to ignore interpolation, since
    # interpolation can't be resolved at this step.
