# Let-Polymorphism and Eager Type Schemes

@inproceedings{Liang1997LetPolymorphismAE, title={Let-Polymorphism and Eager Type Schemes}, author={Chuck Liang}, booktitle={TAPSOFT}, year={1997} }

This paper presents an algorithm for polymorphic type inference involving the let construct of ML in the context of higher order abstract syntax. It avoids the polymorphic closure operation of the algorithm W of Damas and Milner by using a uniform treatment of type variables at the meta-level. The basic technique of the algorithm facilitates the declarative formulation of type inference as goal-directed proof-search in a logical frameworks setting.

### A generator for type checkers

- Computer Science
- 2004

Saga is a novel language design that enables generic algorithms as found in the C STL to be type-checked such that the correctness requirements stated in algorithm interfaces are obeyed and instantiation never fails, and turns the aims of the earlier proposal SuchThat into a concrete language design.

### HM(X) type inference is CLP(X) solving

- Computer ScienceJ. Funct. Program.
- 2008

The HM(X) system is a generalization of the Hindley/Milner system parameterized in the constraint domain X, where X is defined by Constraint Handling Rules, and an inference approach where the HM(x) type inference problem is first mapped to a CLP( X) program is formalized.

### Type inference in the presence of overloading, subtyping and recursive types

- Computer ScienceLFP '92
- 1992

A unified approach to type inference in the presence of overloading and coercions based on the concept of constraint sets is presented and the decidability of type inference for the class of decomposable predicates is proved.

### What are principal typings and what are they good for?

- MathematicsPOPL '96
- 1996

The pragmatic value of the principal typing property is demonstrated, a property distinct from ML's principal type property, by studying a type system with principal typings that provides elegant support for separate compilation, including "smartest recompilation" and incremental type inference.

### Polymorphic type inference

- Computer SciencePOPL '83
- 1983

This paper deals with type inference for parametric type systems, that is --- type systems that includesple types defied over constant types and type variables, and presents an alternative algorithm V for type inference,fundamentally different from W, which easily accommodates typecoercion and overloading, allows efficient local updates to theuser program, and is more efficient than W for implementations that allow concurrency.

Higher-order abstract syntax incorporates name binding information in a uniform and language generic way and acts as a powerful link integrating diverse tools in program manipulation and other formal systems where matching and substitution or unification are central operations.
