This is designed to complement
Awaitthat was added in PR #205. WhileAwaitbehaves most closely to a iterating a sequence of results where a result must be a successful evaluation of the asynchronous function,AwaitCompletionenables the user to await completions such that the sequence iteration doesn't fail as a result of the failure of any one asynchronous evaluation. This allows the user to see the tasks as results and then decide what to do with them (e.g. retry the failures).
