cut
Returns this list, with all elements not in the range from..to removed.
Functionally equivalent to MutableList.subList but effects this list, not returning a copy with the specified elements.
this method is no-alloc, like other methods in this family such as fastEach.
This method is not thread safe. If the original list is being iterated over when this method is called, it will probably blow up.
