      Add path segment /$each to apply an operation on each item of a collection, executed all-or-nothing atomically:

      DELETE Orders/$filter=@f/$each?@f=Age gt 3
      PATCH Orders/$each - with single payload
      PATCH Orders - with delta payload
      POST Orders/$filter=@f/$each/Some.SingleAction?@f=Age gt 2 - binding parameter is single order
      POST Orders/$filter=@f/Some.CollectionAction?@f=Age gt 2 - binding parameter is collection of orders

      Description

      As of 4.01 we support PATCH to a collection of entities. The PATCH is either interpreted as a set operation (if the payload is a single entity) or applied as a delta payload (if the payload has a context URL of #$delta.

      Rather than distinguishing on payload, what if we said that PATCH to a collection of entities is always interpreted as an operation on the set as a whole, and a new path segment /$each is used for an atomic operation on each of the entities, especially DELETE, and PATCH with a single-instance payload.
