With Chris Travers recently going O-R gung-ho on us I decided I wanted to find out where in the documentation the following behavior is specified: The _expression_: (some_composite).calculated_field resolves to the function call: calculated_field(some_composite) I know I’ve seen it before, though whether in the docs or in e-mail I am unsure, but for the life of me browsing for it for about 10 minutes got me nowhere – and I am not sure how to construct a meaningful search which would be a secondary means to discover the information IMO. I am beginning to see the value in having such a syntax but it seems unusual enough that if it is indeed as powerful as Chris is discovering I would think finding and espousing on its existence/features in the documentation would be important. Given that it has to do with functions and composite types it should probably appear in both (and Advanced Features even) with cross-references between the various locations. Thoughts/Comments/Directions?
