 The library comes with two free functions, one with a generic clock. And another one which uses the `ContinuousClock` as default.
 ```swift
-public func withDeadline<C, T>(
+public func withDeadline<C, R>(
   until instant: C.Instant,
   tolerance: C.Instant.Duration? = nil,
   clock: C,
-  operation: @escaping @Sendable () async throws -> T

+  operation: @Sendable () async throws -> R

 ```
 
 This function provides a mechanism for enforcing timeouts on asynchronous operations that lack native deadline support. It creates a `TaskGroup` with two concurrent tasks: the provided operation and a sleep task.
