(1) -> SI ==> Set Integer
Type:
Void
(2) -> SSI ==> Set SI
Type:
Void
(3) -> si:SI := set [2]
(3) {2}
Type: Set(Integer)
(4) -> subset?(si,si)
(4) true
Type: Boolean
(5) -> ssi: SSI := set [si]
(5) {{2}}
Type: Set(Set(Integer))
(6) -> subset?(ssi,ssi)
(6) false
Type: Boolean
Why does (6) give false? Either that is a bug or I must be doing
something wrong. But what?
