Casting 'record' to a composite type.

Hello,
When using functions that return the datatype 'record', rather than
doing this:

SELECT *
FROM fn_returning_setof_record( ... )
AS t (id integer, title text);

I'd like to do something like this:

CREATE TYPE my_type AS (id integer, title text);

SELECT *
FROM fn_returning_setof_record( ... )
AS t my_type;
or
SELECT *
FROM fn_returning_setof_record( ... )::my_type AS t;

Obviously the last two statements don't work, but you can see what I'm
getting at,
casting the 'record' datatype to a composite datatype.
I've not been able to find anything like this in the docs.
Is there currently any way of doing this? are there any plans for it?

Cheers
