It'd definitely be nicer that way, but given the current limitations of
bootstrap mode I see no non-kluge way to make a built-in function have
OUT parameters. (Hint: array_in doesn't work in bootstrap mode.)
And the other alternatives like a predefined complex type seem even
more painful. If you can think of a way to do this that has pain
not out of proportion to the gain, then I'm all for it ...
