def await(future_or_value)
  if future_or_value.is_a?(Concurrent::Promises::Future)
    future_or_value.value!
  else
    future_or_value
  end
end

#await_all(*args) ⇒ Object

wait for all promises. REMARK: This method doesn’t assure the order of calling. for example, await_all(async1, async2) calls calls2 -> calls1 often.

def await_all(*args)
  if args.length == 1 && args[0].is_a?(Enumerable)
    Concurrent::Promises.zip(*(args[0])).value!
  else
    Concurrent::Promises.zip(*args).value!
  end
end

#await_any(*args) ⇒ Object

wait for first promises. REMARK: This method doesn’t assure the order of calling. for example, await_all(async1, async2) calls calls2 -> calls1 often.
