Overview

This class is abstract.

The abstract base class for Sass visitors. Visitors should extend this class, then implement `visit_*` methods for each node they care about (e.g. `visit_rule` for RuleNode or `visit_for` for ForNode). These methods take the node in question as argument. They may `yield` to visit the child nodes of the current node.

Note: due to the unusual nature of IfNode, special care must be taken to ensure that it is properly handled. In particular, there is no built-in scaffolding for dealing with the return value of `@else` nodes.
