    `boolean` | `visit(AstNode node)` Visits an AST node.

- - ### Method Detail

    - #### visit

          boolean visit(AstNode node)

      Visits an AST node.
      Parameters:
        `node` - the AST node. Will never visit an `AstRoot` node, since the `AstRoot` is where the visiting begins.
      Returns:
        `true` if the children should be visited. If `false`, the subtree rooted at this node is skipped. The `node` argument should never be `null` -- the individual `AstNode` classes should skip any children that are not present in the source when they invoke this method.
