Score: 6.3/10 (Innovation: 7, Technical: 7, Documentation: 6, Utility: 5)

Effecton is a typed algebraic effect system for Python inspired by Effect-TS, bringing structured error handling, dependency injection, retries, and observability via generators. It offers a novel way to compose side effects with static typing in Python, though early-stage with limited adoption.

Target audience: Python backend developers interested in functional programming and type-safe effect handling
