Not quite. Setting length will copy over the existing contents of 
the array. Using new simply sets every element to .init.

Granted, this.data is empty meaning there's nothing to copy over, 
so there's a negligible overhead which may be optimized out by 
the compiler anyways.

There's also the uninitializedArray function:
