Set operations
They try to be set-like, supporting most of the operations that the set
object does.
Actually, dunno how much of this I’m missing. Raise a ticket if there are gaps.

A ⋂ B |
intersection | A & B |
A ⋃ B |
union | A | B |
A ⊆ B |
subset | A <= B |
A ⊂ B |
proper subset | A < B |
A ⊇ B |
superset | A >= B |
A ⊃ B |
proper superset | A > B |
A = B |
equality | A == B |
A' |
complement | ~A |
A \ B |
relative complement | A - B |
A ∆ B |
symmetric difference | (A | B) - (A & B) |
a ∈ A |
membership | a in A |
|A| |
