> Collections of entities and complex type instances are now treated equally, but collections of primitive values are somewhat neglected. They do allow the path suffix /$count, and the query options $count, $top and $skip are straight-forward.
> For $filter and $orderby we need one tiny generalization: we currently allow common expressions within the lambda operators any() and all() to use $it for addressing the current entity, and we can use that to filter collections of primitive values:
> GET ~/Customers(1)/EmailAddresses?$filter=endswith($it,'.com')
> This increased flexibility is also useful for querying collections of entities:
> GET ~/Employees?$filter=$it eq Manager
> Would return all employees who are their own manager.
> This also allows retrieving the entity for a given reference:
> GET ~/Employees?filter=$it eq { odata.id: .... }
