No (it was discussed some many months ago). It may looks like a  =

write=E2=80=91in=E2=80=91place statement, but that's only an appearance,=
 nothing specifies  =

it should have this behavior. For non=E2=80=91limited types, the extende=
d return  =

statement is exactly the same as a classic return statement, wrapped in =
a  =

local scope (as with a declare/begin/end block) with a locally declared =

variable. Nothing special with this construct when not applied to a  =

limited type.
