Experience using constraint programming to solve real-life problems has shown that finding an efficient solution to the problem often requires experimentation with different constraint solvers or even building a problem-specific constraint solver. HAL is a new constraint logic programming language expressly designed to facilitate this process. It provides semi-optional type, mode and determinism declarations. These allow natural constraint specification by means of type overloading, better compile-time error checking and generation of more efficient run-time code. Importantly, it provides type classes which can be used to specify solver interfaces, allowing the constraint programmer to support modelling of a constraint problem independent of a particular solver, leading to easy plug and play experimentation with different solvers. Other interesting features include mutable global variables for implementing a constraint store, and dynamic scheduling and Constraint Handling Rules (CHRs) for combining, extending and writing new constraint solvers.
