checkssuch

Checkssuch is a term used in discussions of software testing, formal verification, and query processing to denote a predicate or routine that verifies whether a dataset, state, or element satisfies a specified collection of properties. The name is a portmanteau of “checks” and “such,” intended to convey the idea of performing checks for a particular set of conditions.

In practice, a checkssuch function or method receives a domain (such as a data structure, input stream, or model state) and a list or conjunction of condition predicates. It returns true when there exists or all elements in the domain that meet the specified properties, depending on the intended semantics. A common formulation is to evaluate a conjunction of predicates: cond1(x) and cond2(x) and …, often expressed in logic as exists x in D such that cond1(x) ∧ cond2(x) ∧ ….

Variants of the concept appear in various contexts. In query languages, checkssuch-style queries identify items that satisfy a set of constraints. In property-based testing, they map to tests that confirm multiple properties hold simultaneously. In formal methods, they relate to existential or universal checks used during model checking and proof generation.

Limitations include potential computational complexity and readability challenges when many predicates are involved. Well-designed checkssuch constructions favor clear specification of properties and efficient evaluation order to minimize unnecessary computation.
