Use Option[T] to model nullable values in Go, wrapping presence or absence safely to eliminate nil pointer panics. You can extract and transform values through safe constructors without risking runtime crashes.

Use Result[T] to model fallible operations in Go, chaining them into functional pipelines that short-circuit automatically on errors. This replaces repetitive if-err checks with composable, type-safe transformations.

Use Either[L, R] in Go when both sides are valid alternatives rather than success versus error, such as choosing between cached and fresh data paths. Result[T] is specifically for fallible computations that return errors.

Yes, Go 1.18+ generics are required because monadic abstractions like Option, Result, and Either rely on generic type parameters to enforce type safety across functional pipelines and nullable fields.

Use the option, result, and either sub-packages to apply type-changing transformations within a Go pipeline. PipeN functions enable readable, multi-step flows that safely convert types across successive operations.

Yes, these monadic abstractions provide explicit control over side effects and async execution within Go functional pipelines. You model alternative flows and fallible computations safely without hidden state changes.
