because in my project, first post, there is a disabled "sub ugly" and it don't like me.
you proposed same "sub and wait for" !!!
many and many "wait for" ...

maybe it's only way possible to "return" parameter ?
why it is not possible?
Private Sub doSomething As List
'(resumable subs return type must be resumable or none) error !!! why???
DoBigJobs
Wait For okJobs (result As List)
Log ("=== here is ok ===")
For i = 0 To result.Size - 1
Log(result.Get(i))
Next
return result 'error !!!! why?
End Sub
it is easy
sub Easy as list
dim myList as list
....
...
..
return myList
end sub
