Logic Bomb... Retrieving "negative" index, and wrap around an Array?

[Ralgoth]

That would cause more problems. If you use arrays to keep track of objects, especially when using multi-dimensional arrays, you would no longer have the ability to see if an object has been set for a particular cell. Example...

say that I want to get a bitmap from my array that has an index of 16. I would normally retrieve with something like this...

function getBitmap(n:uint):BitmapData
{
   return myArray[n] ||= bitmapLoader(n);
}

var bmp:BitmapData = getBitmap(16);

so the function above would either return the BitmapData that's stored in myArray[n] or load and return a new bitmap. With the index-wrapping feature, that would no longer be the case.

--- edit ---

though, that's not to say that the function itself wouldn't be useful. Just, as a static function either in Math or Array, and not implemented as a default.
