Bug Description
It would be useful to me to be able to remove tuples selected by a sliced query, i.e. "delete x rows from this result set." It helps spread out garbage collection so as not to overload our databases.
I imagine the complication would be to identify a key that can be selected in a limited sub-query and passed to a surrounding DELETE query.

This could probably be implemented similar to how Store._ _contains_ _() handles non-trivial cases by using replace_columns() to generate a subquery expression.
