Withsets

Withsets is a term used in discussing operations that involve a collection of sets treated together. It is not a standard mathematical or programming operator, but appears in niche documentation and hypothetical language proposals as a convenient shorthand for batch set processing.

In programming contexts, withsets can refer to a scope or context manager that binds several sets to local names within a block. The construct emphasizes that the sets are temporary, to be used for a sequence of operations and then discarded, reducing pollution of the outer scope and clarifying the intent to operate over a bundle of sets at once.

In data processing libraries, withsets may denote an API that accepts multiple input sets and returns results produced by setwise operations or by combining elements across sets. Typical operations include union, intersection, and difference, as well as product-like constructions. Implementations may choose eager or lazy evaluation and may offer utilities to map results back to the original identifiers.

In mathematics or formal logic, withsets can be used informally to refer to a family of sets considered together, or to describe constructions that couple sets under a common condition or relation.

Example: withsets A, B: C = A ∪ B; D = A ∩ B. In a hypothetical language, a more explicit form might be withsets (A, B) do ... end. See also: Set, Set theory, Union, Intersection, Context manager.
