     * Creates a `lodash` object which wraps `value` to enable implicit method
     * chain sequences. Methods that operate on and return arrays, collections,
     * and functions can be chained together. Methods that retrieve a single value
     * or may return a primitive value will automatically end the chain sequence
     * and return the unwrapped value. Otherwise, the value must be unwrapped
     * with `_#value`.
     *
     * Explicit chain sequences, which must be unwrapped with `_#value`, may be
     * enabled using `_.chain`.
     *
     * The execution of chained methods is lazy, that is, it's deferred until
     * `_#value` is implicitly or explicitly called.
     *
     * Lazy evaluation allows several methods to support shortcut fusion.
     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
     * the creation of intermediate arrays and can greatly reduce the number of
     * iteratee executions. Sections of a chain sequence qualify for shortcut
     * fusion if the section is applied to an array and iteratees accept only
     * one argument. The heuristic for whether a section qualifies for shortcut
     * fusion is subject to change.
     *
     * Chaining is supported in custom builds as long as the `_#value` method is
     * directly or indirectly included in the build.
     *
     * In addition to lodash methods, wrappers have `Array` and `String` methods.
     *
     * The wrapper `Array` methods are:
     * `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
     *
     * The wrapper `String` methods are:
     * `replace` and `split`
     *
     * The wrapper methods that support shortcut fusion are:
     * `at`, `compact`, `drop`, `dropRight`, `dropWhile`, `filter`, `find`,
     * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
     * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
     *
     * The chainable wrapper methods are:
     * `after`, `ary`, `assign`, `assignIn`, `assignInWith`, `assignWith`, `at`,
     * `before`, `bind`, `bindAll`, `bindKey`, `castArray`, `chain`, `chunk`,
     * `commit`, `compact`, `concat`, `conforms`, `constant`, `countBy`, `create`,

     * `difference`, `differenceBy`, `differenceWith`, `drop`, `dropRight`,

     * should be invoked on the leading and/or trailing edge of the `wait`

     * throttled function. Subsequent calls to the throttled function return the
     * result of the last `func` invocation.

     * invoked on the trailing edge of the timeout only if the throttled function
     * is invoked more than once during the `wait` timeout.

 *  WebSocket provider assumes the connected backend will manage this.
 *
 *  For example, if a polling provider emits an event which indicates
 *  the event occurred in blockhash XXX, a call to fetch that block by
 *  its hash XXX, if not present will retry until it is present. This
 *  can occur when querying a pool of nodes that are mildly out of sync

/**
 * 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

 *     });
 *
 * 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 the
 * visitor API:
 *
 * 1) Named visitors triggered when entering a node of 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
 *         }
