elseBlock function

Implementation

Parser elseBlock() => seq2(
      ref0(elseTag),
      ref0(elseBranchContent),
    ).map((values) {
      final elseTag = values.$1;
      final elseBody = (values.$2 as List).cast<ASTNode>();
      return elseTag.copyWith(body: elseBody);
    }).labeled('elseBlock');
