## Description

Flix is a statically typed multi-paradigm programming language that combines functional, imperative, and logic programming paradigms within a single unified environment. It utilizes a constraint-driven execution environment to derive results by satisfying logical predicates rather than following linear sequential instructions.

The language features a unification-based logic engine designed to solve complex computational problems through term unification and backtracking. This is supported by a core library of persistent immutable data structures that ensure side-effect free state management across its various programming styles.

The system provides a unified static type checker to validate functional, imperative, and logic constructs, utilizing a statically typed intermediate representation to maintain safety during translation to machine instructions.
