To handle nullable values safely in Go, you can use the Option[T] monad to model optional values explicitly. This ensures safe access and supports JSON and database readiness by avoiding direct nil checks.

The best way to propagate errors in a Go functional pipeline is using the Result[T] monad. It represents success or failure explicitly and provides helpers for mapping and chaining operations without disrupting the pipeline flow.

Yes, you can represent discriminated unions in Go using the Either[L, R] monad. It models scenarios where two valid alternatives exist, allowing your code to handle both left and right states safely.

You can compose multi-step transformations in Go using Do notation and pipeline sub-packages. These features allow you to chain Option, Result, and Either monads together for complex functional workflows.

No specific framework is required, but you need a standard Go project environment. You simply install the samber/mo module and import the monadic types to start building type-safe functional pipelines for error handling and nullable values.
