mootools breaks array comprehensions

[murat]

mootools appears to extend Array in a manner that spoils the ability to use array comprehensions (see http://developer.mozilla.org/en/docs/New_in_JavaScript_1.7#Array_comprehensions)

Here's an example:

var numbers = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
var someThings = [n for each (n in numbers)]; 

After executing the above code, someThings should be an array just like numbers, but if you examine it in a debugger or do something like alert(someThings), you'll see that someThings includes extra mootools baggage. This makes array comprehensions pretty much unusable.

use numbers.each instead, if not supported by your browser, mootools catch and emulate it.
