Set consolidation
multi consolidate() { () }
multi consolidate(Set \this is copy, *@those) {
gather {
for consolidate |@those -> \that {
if this ∩ that { this = this ∪ that }
else { take that }
}
take this;
}
}
enum Elems <A B C D E F G H I J K>;
say $_, "\n ==> ", consolidate |$_
for [set(A,B), set(C,D)],
[set(A,B), set(B,D)],
[set(A,B), set(C,D), set(D,B)],
[set(H,I,K), set(A,B), set(C,D), set(D,B), set(F,G,H)];
Output:
set(A, B) set(C, D)
==> set(C, D) set(A, B)
set(A, B) set(B, D)
==> set(A, B, D)
set(A, B) set(C, D) set(D, B)
==> set(A, B, C, D)
set(H, I, K) set(A, B) set(C, D) set(D, B) set(F, G, H)
==> set(A, B, C, D) set(H, I, K, F, G)
