It struck me that the ability to pass a coderef (sorry, delegate :) to the sort
method
that was called back with both the [index, value] or [key,value] of the items
being
compared and returning -1, 0, +1, would allow for custom sorting.

The other notion that crossed my mind was having the ability to locally (scoped)
override the opCmp of built-in types, but that would require all opCmps to 
expect two pairs.
