+/**
+ * Apply a visitor to an AST node or document.
+ *
+ * Walks through the tree (depth-first) starting from `node`, calling a
+ * `visitor` function with three arguments:
+ *   - `key`: For sequence values and map `Pair`, the node's index in the
+ *     collection. Within a `Pair`, `'key'` or `'value'`, correspondingly.
+ *     `null` for the root node.
+ *   - `node`: The current node.
+ *   - `path`: The ancestry of the current node.
+ *
+ * The return value of the visitor may be used to control the traversal:
+ *   - `undefined` (default): Do nothing and continue
+ *   - `visit.SKIP`: Do not visit the children of this node, continue with next
+ *     sibling
+ *   - `visit.BREAK`: Terminate traversal completely
+ *   - `visit.REMOVE`: Remove the current node, then continue with the next one
+ *   - `Node`: Replace the current node, then continue by visiting it
+ *   - `number`: While iterating the items of a sequence or map, set the index
+ *     of the next step. This is useful especially if the index of the current
+ *     node has changed.
+ *
+ * If `visitor` is a single function, it will be called with all values
+ * encountered in the tree, including e.g. `null` values. Alternatively,
+ * separate visitor functions may be defined for each `Map`, `Pair`, `Seq`,
+ * `Alias` and `Scalar` node. To define the same visitor function for more than
+ * one node type, use the `Collection` (map and seq), `Value` (map, seq & scalar)
+ * and `Node` (alias, map, seq & scalar) targets. Of all these, only the most
+ * specific defined one will be used for each node.
