Sorry for delay. I am still thinking about API.
1) It is normal that we need to use result of destructive
operation and can not relay on side effects.
2) It is disturbing of side effect appear on argument of
'construct' (which may happen if we omit copy during 'construct').
3) It is very disturbing that results of 'parts' may be modified
by destructive operations on aggregate:
(1) -> q := queue([1, 2, 3])$Queue(Integer)
(1) [1,2,3]
Type: Queue(Integer)
(2) -> l := parts(q)
(2) [1,2,3]
Type: List(Integer)
(3) -> enqueue!(0, q)
(3) 0
Type: NonNegativeInteger
(4) -> l
(4) [1,2,3,0]
Type: List(Integer)
