Code Review

What this skill does


# Type Inference Engine

## Purpose

Provides expert guidance on implementing type inference algorithms for programming language implementations.

## Capabilities

- Algorithm W implementation
- Constraint generation and solving
- Unification with occurs check
- Let-polymorphism (Hindley-Milner)
- Principal type computation
- Type error diagnosis

## Usage Guidelines

1. **Constraint Generation**: Generate type constraints from expressions
2. **Unification**: Implement unification algorithm
3. **Generalization**: Handle let-polymorphism
4. **Error Messages**: Generate informative type errors
5. **Testing**: Validate inference on test cases

## Tools/Libraries

- Language workbenches
- Constraint solvers
- Type inference libraries
