[flexcoders] bug in Array.splice?

[Pan Troglodytes]

Either there is a bug in Array.splice, or the documentation is off.

From the help:

Example
The following code creates the Array object vegetables with the elements [spinach, green pepper, cilantro, onion, avocado]. The splice() method is then called with the parameters 2 and 2, which assigns cilantro and onion to the spliced array. The vegetables array then contains [spinach,green pepper,avocado]. The splice() method is called a second time using the parameters 1, 0, and the spliced array to assign [spinach,cilantro,onion,green pepper,avocado] to vegetables.

var vegetables:Array = new Array("spinach",
                 "green pepper",
                 "cilantro",
                 "onion",
                 "avocado");


var spliced:Array = vegetables.splice(2, 2);
trace(vegetables); // spinach,green pepper,avocado
trace(spliced);    // cilantro,onion

vegetables.splice(1, 0, spliced);
trace(vegetables); // spinach,cilantro,onion,green pepper,avocado

However, this is not the case.  When you pass an array as the third argument to splice, it adds the target ARRAY to the original array.  It does not insert the VALUES in the target array.

if you add
for each (var o:Object in vegetables)
  trace(typeof(o), o.toString());


you will get:
string spinach
object cilantro,onion
string green pepper
string avocado

So, is this a bug or intended behavior?  I could see how it could go either way.  However, it seems the example in the documentation should be fixed.  I'm thinking it was intended that a passed-in array would be disassembled and its components added.  Otherwise, why say "one or more comma-separated values, or an array, to insert into the array"?  Singling out array makes no sense, as it would be treated like any other value passed in.
