I'd be pretty happy to have
(a, b) = (x, y);
(a, b) = f(x);
which is SQL-esque.
This is not too far to my proposal - and it is fully adequate alternative.
But what, if anything, does Ada do?
What I know, no, Ada has not this statement - but the design of OUT parameters in Ada absolutely different than PostgreSQL - so in this case we cannot to use Ada language as our base :(
