## What it is
A Swift microframework providing a Result<Value, Error> type that models operations as either success or failure, similar to Optional but with an associated error. It offers composable map/flatMap operations as an alternative to Swift's throw-based error handling.

## Use cases
- model success/failure of operations in Swift
- return errors as values instead of throwing
- compose fallible operations with map and flatMap
- pattern match on operation outcomes with switch
- share a common Result type across Swift frameworks

## When to choose
- you're on an older Swift codebase (pre-5.0) without a native Result type
- you want composable, value-based error handling with map/flatMap
- you need interoperability with other frameworks using this Result type

## When to avoid
- you're on Swift 5+ where Result is in the standard library
- you prefer Swift's native throw/catch error handling
- starting a new project with no legacy dependencies on this library
