What problem does it solve?

Monadic patterns in Go provide explicit handling for absence, errors, and multiple outcomes, reducing boilerplate and improving type safety.

Core Features & Use Cases

• Option for nullable data with explicit presence/absence, enabling safer JSON and DB modeling.
• Result and Either abstractions to model errors and alternative data flows, with Do notation and pattern matching.
• Pipeline sub-packages (option, result, either) for type-changing transformations, enabling readable multi-step pipelines.
• Interoperability with standard library calls via TupleToResult, Try, Map, and FlatMap.

Quick Start

Convert a Go function’s (value, error) result with TupleToResult and then apply a simple Map transformation to demonstrate chainable error handling.
