Higher-Order Contracts Sample Clauses

Higher-Order Contracts. ‌ The base contracts in Section 4.1 and Section 4.2 specify flat statements on primitive values that may be true or false depending on the subject values. Even though straightforward assertions of base contracts may also test properties on functions and objects, they are not expressive enough to state higher-order properties of functions and objects that cannot be checked immediately. For example, a contract should be able to express that a function plus maps two number values to a number value or that the access to the length property of an array object always returns a number value. Hence, higher-order contracts are needed to address first-class functions and other advanced abstractions. To this end, TreatJS provides several kinds of higher-order contracts. In general, a higher-order contract is a contract that takes one or more contracts for the domain of an operation and that returns a contract for the range of an operation.

Higher-Order Contracts. Enforcing pre- and post-conditions at runtime is a widely established practice. In their foundational paper[11], Xxxxxxx and Felleisen introduce higher-order contracts, a principled approach to run-time assertion checking that nicely sup- ports functions. They introduce the notion of blame, which is crucial to good error reporting. It became apparent later that their contracts are closely related to the type casts in- troduced by gradual typing, excluding blame: both [15] and [19] see the value of contracts as a safe interface between typed and untyped code. In [21], the authors precisely in- troduce a system integrating gradual typing with contracts à xx Xxxxxxx & Felleisen. Nickel adopts a similar type system, with both statically typed terms, dynamically typed terms, and first-class contracts. Higher-order contracts are the ba- sis of the work [14] and [22] that this paper explorted exten- sively.
