If you want to swap elements x and y in an array:

element [x][y].swap();

makes no sense.

Your function would have to be something like:

array.swap_elements(x,y);

But why would you ever need to do this except in the context of sorting? 
An array is either ordered or unordered - if it's unordered it doesn't 
matter what order the elements are in, and if you want it ordered 
according to some specific algorithm, just write a custom sort function 
and sort with it:

array.sort(sortfunction);

where:

sortfunction( a, b ) {}

returns <0 if a comes first, >0 if b comes first, 0 if they're equal.
