evaluate(@tags)
       Returns "true" when the tag set specified in $tags satisfies the condition(s) of the expression, "false"
       otherwise.

       @tags can be a list of tags to be used in the expression. It can also be a reference to a hash with the
       keys being the tags and the values being considered boolean values indicating whether the tag (key) is
       considered part of the tagset (true) or not (false).

   stringify
       Returns a string representation of the expression node.

Cucumber::TagExpressions::LiteralNodeDESCRIPTION

       This node class returns "true" if the literal tag is specified as part of the tag-list in the expression
       evaluation.

       ATTRIBUTES

       tag

       The tag to test presence for.

   Cucumber::TagExpressions::AndNodeDESCRIPTION

       This node class type evaluates one or more sub-expressions ("terms") and returns "false" if any of the
       terms does. It returns "true" if all of the terms return "true".

       ATTRIBUTES

       terms

       The sub-expressions to evaluate.

   Cucumber::TagExpressions::OrNodeDESCRIPTION

       This node class type evaluates one or more sub-expressions ("terms") and returns "true" if any of the
       terms does. It returns "false" if all of the terms return "false".

       ATTRIBUTES

       terms

       The sub-expressions to evaluate.

   Cucumber::TagExpressions::NotNodeDESCRIPTION

       This class wraps one of the other node class types, negating its result on evaluation.

       ATTRIBUTES

       expression

       The wrapped node class instance for which to negate the result.

   Cucumber::TagExpressions::ExpressionNodeDESCRIPTION

       This class models the outer-most node in the tag expression; it wraps all other nodes and is the entry-
       point for tag expression evaluation.

       ATTRIBUTES

       sub_expression

       An instance of one of the other node class types.

         use Cucumber::TagExpressions;

         my $expr = Cucumber::TagExpressions->parse( '@a and @b' );
         if ( $expr->evaluate( qw/x y z/ ) ) {
            say "The evaluation returned false";
         }
