couldnt this also be written as:

foreach (new T_User('firstname' =3D> $firstname, "ORDERBY" =3D> "age") =
as $user)

of course it would be a bit more work when constructing the final query, =
but its tons clearer in terms of knowing how to use the API with just =
reading one use of the API and not the actual implementation.

in the above code what is the purpose of the positional argument? can i =
just "append" what I want? aka is the idea of the API to also support

foreach (new T_User('firstname' =3D> $firstname, "LIMIT 100") as $user)

and

foreach (new T_User('firstname' =3D> $firstname, "ORDER BY age LIMIT =
100") as $user)

in that case it would still be better to then do:

foreach (new T_User('firstname' =3D> $firstname, 'append' =3D> "ORDER BY =
age") as $user)

.. of course its a few more characters, but its definitely easier to =
grasp whats going on, then having to parse what is named and what is =
positional.

i am trying to remember what killed the discussion last time around. i =
think it was concerns over having to convert all internal functions, but =
i guess that was before we unified the parameter parsing API. IIRC =
hartmut was quite involved in the discussion back then .. maybe he =
remembers.
