Are these two code snippets equivalent?
```val job = SupervisorJob()
val lifecycleScope = CoroutineScope(Dispatchers.Main + job)

lifecycleScope.launch { }```
```val job = SupervisorJob()
val lifecycleScope = CoroutineScope(job)

lifecycleScope.launch(Dispatchers.Main) { }```


I would say not _entirely_ equivalent -- the two `lifecycleScope`s obviously have different final contexts, but the code in `launch` will be run in the same way, if that was the question

ok that was my main question. Why would the context be different? would it need to be
```lifecycleScope.launch(Dispatchers.Main + job) { }```

ie: if I cancel job in the second snippet, it still cancels that `launch` correct?

the context is different in that _any_ `launch` (or async, etc.) would use the Main dispatcher by default in the first one, but only the single launch in the second one uses Main by default

the job cancellation would still work the same

only the `coroutineContext[CoroutineInterceptor]` would differ -- no other element
