> In OData-1105 we introduced $select options which enabled filtering a collection of structural properties.  Where the collection is a collection of complex types, you can now do something like:
> Customers?$select=Addresses($filter=City eq 'Paris')
> However, we don't have a way to filter primitive types.
> We also don't have a way, in $select or $expand, to pass the current item into a function without binding the function to the type of the current item.
> We already have $it that references the resource identified by the last segment of the resource path, but in this case we want to reference the property on which the select/expand options are specified.
