	/**
	 * visit() will walk through an AST using a depth first traversal, calling
	 * the visitor's enter function at each node in the traversal, and calling the
	 * leave function after visiting that node and all of its child nodes.
	 *
	 * By returning different values from the enter and leave functions, the
	 * behavior of the visitor can be altered, including skipping over a sub-tree of
	 * the AST (by returning false), editing the AST by returning a value or null
	 * to remove the value, or to stop the whole traversal by returning BREAK.
	 *
	 * When using visit() to edit an AST, the original AST will not be modified, and
	 * a new version of the AST with the changes applied will be returned from the
	 * visit function.
	 *
	 *     const editedAST = visit(ast, {
	 *       enter(node, key, parent, path, ancestors) {
	 *         // @return
	 *         //   undefined: no action
	 *         //   false: skip visiting this node
	 *         //   visitor.BREAK: stop visiting altogether
	 *         //   null: delete this node
	 *         //   any value: replace this node with the returned value
	 *       },
	 *       leave(node, key, parent, path, ancestors) {
	 *         // @return
	 *         //   undefined: no action
	 *         //   false: no action
	 *         //   visitor.BREAK: stop visiting altogether
	 *         //   null: delete this node
	 *         //   any value: replace this node with the returned value
	 *       }
	 *     });
	 *
	 * Alternatively to providing enter() and leave() functions, a visitor can
	 * instead provide functions named the same as the kinds of AST nodes, or
	 * enter/leave visitors at a named key, leading to four permutations of
	 * visitor API:
	 *
	 * 1) Named visitors triggered when entering a node a specific kind.
	 *
	 *     visit(ast, {
	 *       Kind(node) {
	 *         // enter the "Kind" node
	 *       }
	 *     })
	 *
	 * 2) Named visitors that trigger upon entering and leaving a node of
	 *    a specific kind.
	 *
	 *     visit(ast, {
	 *       Kind: {
	 *         enter(node) {
	 *           // enter the "Kind" node
	 *         }
	 *         leave(node) {
	 *           // leave the "Kind" node
	 *         }
	 *       }
	 *     })
	 *
	 * 3) Generic visitors that trigger upon entering and leaving any node.
	 *
	 *     visit(ast, {
	 *       enter(node) {
	 *         // enter any node
	 *       },
	 *       leave(node) {
	 *         // leave any node
	 *       }
	 *     })
	 *
	 * 4) Parallel visitors for entering and leaving nodes of a specific kind.
	 *
	 *     visit(ast, {
	 *       enter: {
	 *         Kind(node) {
	 *           // enter the "Kind" node
	 *         }

	 *       leave: {
