Subject: Delete elements in array, break, and keep changes?

I have an array of a lot elements that I need to cluster (they are
latitudes and longitudes).

As I iterate the array I want to remove elements that I have already
clustered.

Currently I've tried using Array::reject! and Array::delete_if. It
works. I can further optimize by breaking from the delete_if/reject!
block if certiain conditions are met.

Here is the issue, if I call break in the block, all of the changes to
the array are lost.

Is there a way to break from the block but still delete/reject elements
in the array?
