 ## Introduction
 
 Swift Concurrency uses tasks and actors to model concurrency and primarily relies on actor isolation to determine where a specific piece of code shall execute.

 Once set, the effect of an executor preference is such that a nonisolated func instead of immediately hopping to the global pool, it may hop to the preferred executor, e.g.:
 
 ```swift
-nonisolated func tryMe() async { 
+nonisolated func doSomething() async { 
  // ...
 }
 
 let preferredExecutor: SomeConcreteTaskExecutor = ...
 Task(on: preferredExecutor) {
   // executes on 'preferredExecutor'
-  await tryMe() // tryMe body would execute on 'preferredExecutor'
+  await doSomething() // doSomething body would execute on 'preferredExecutor'
 }
 
- await tryMe() // tryMe body would execute on 'default global concurrent executor'
+ await doSomething() // doSomething body would execute on 'default global concurrent executor'
 ```
