asyncio.wait has 3 different options to run with

Constant Description
FIRST_COMPLETED The function will return when any future finishes or is cancelled.
FIRST_EXCEPTION The function will return when any future finishes by raising an exception. If no future raises an exception then it is equivalent to ALL_COMPLETED.
ALL_COMPLETED The function will return when all futures finish or are cancelled.

but there is no way to run it in 4-th mode FIRST_COMPLETED + FIRST_EXCEPTION
which is "must-have" in the case when it suppose to wait for iterator
it will send totally legit Exception about end of iteration
but asyncio.wait has no way to catch/handle it properly.
