 {{alias}}( collection, [options,] predicate, done )
     Tests whether all elements in a collection fail a test implemented by a
     predicate function, iterating from right to left.
 
     When invoked, the predicate function is provided a maximum of four
     arguments:
 
     - `value`: collection value
     - `index`: collection index
     - `collection`: the input collection
     - `next`: a callback to be invoked after processing a collection `value`
 
     The actual number of provided arguments depends on function length. If the
     predicate function accepts two arguments, the predicate function is
     provided:
 
     - `value`
     - `next`
 
     If the predicate function accepts three arguments, the predicate function is
     provided:
 
     - `value`
     - `index`
     - `next`
 
     For every other predicate function signature, the predicate function is
     provided all four arguments.
 
     The `next` callback takes two arguments:
 
     - `error`: error argument
     - `result`: test result
 
     If a provided function calls the `next` callback with a truthy `error`
     argument, the function suspends execution and immediately calls the `done`
     callback for subsequent `error` handling.
 
     The function immediately returns upon encountering a truthy `result` value
     and calls the `done` callback with `null` as the first argument and `false`
     as the second argument.
 
     If all elements fail, the function calls the `done` callback with `null` as
     the first argument and `true` as the second argument.
 
     Execution is *not* guaranteed to be asynchronous. To guarantee asynchrony,
     wrap the `done` callback in a function which either executes at the end of
     the current stack (e.g., `nextTick`) or during a subsequent turn of the
     event loop (e.g., `setImmediate`, `setTimeout`).
 
     The function does not support dynamic collection resizing.
 
     The function does not skip `undefined` elements.
 
     Parameters
     ----------
     collection: Array|TypedArray|Object
         Input collection over which to iterate. If provided an object, the
         object must be array-like (excluding strings and functions).
 
     options: Object (optional)
         Function options.
 
     options.limit: integer (optional)
         Maximum number of pending invocations. Default: Infinity.
 
     options.series: boolean (optional)
         Boolean indicating whether to process each collection element
         sequentially. Default: false.
 
     options.thisArg: any (optional)
         Execution context.
 
     predicate: Function
         The test function to invoke for each element in a collection.
 
     done: Function
         A callback invoked either upon processing all collection elements or
         upon encountering an error.
 
     Examples
     --------
     // Basic usage:
     > function predicate( value, next ) {
     ...     setTimeout( onTimeout, value );
     ...     function onTimeout() {
     ...         console.log( value );
     ...         next( null, false );
     ...     }
     ... };
     > function done( error, bool ) {
     ...     if ( error ) {
     ...         throw error;
     ...     }
     ...     console.log( bool );
     ... };
     > var arr = [ 1000, 2500, 3000 ];
     > {{alias}}( arr, predicate, done )
     1000
     2500
     3000
     true
 
     // Limit number of concurrent invocations:
     > function predicate( value, next ) {
     ...     setTimeout( onTimeout, value );
     ...     function onTimeout() {
     ...         console.log( value );
     ...         next( null, false );
     ...     }
     ... };
     > function done( error, bool ) {
     ...     if ( error ) {
     ...         throw error;
     ...     }
     ...     console.log( bool );
     ... };
     > var opts = { 'limit': 2 };
     > var arr = [ 1000, 2500, 3000 ];
     > {{alias}}( arr, opts, predicate, done )
     2500
     3000
     1000
     true
 
     // Process sequentially:
     > function predicate( value, next ) {
     ...     setTimeout( onTimeout, value );
     ...     function onTimeout() {
     ...         console.log( value );
     ...         next( null, false );
     ...     }
     ... };
     > function done( error, bool ) {
     ...     if ( error ) {
     ...         throw error;
     ...     }
     ...     console.log( bool );
     ... };
     > var opts = { 'series': true };
     > var arr = [ 1000, 2500, 3000 ];
     > {{alias}}( arr, opts, predicate, done )

     1000
     true
