Module `Value.Union`

Union of value abstractions.

This combiner implements a disjoint union between 𝑚 value abstractions 𝒱₁, ..., 𝒱ₘ. Each abstraction 𝒱ᵢ represent values of types 𝐓ᵢ, such that: ∀ j ≠ i: 𝐓ᵢ ∩ 𝐓ⱼ = ∅. The types represented by the combiner is 𝐓₁ ∪ ... ∪ 𝐓ₘ.

The union is represented with a cartesian product. The concretization of a union of values is the union of the concretizations: γ(v₁,...,vₘ) = γ₁(v₁) ∪ ... ∪ γₘ(vₘ).
