def every(coro, iterable, limit=1, loop=None):
    """
    Returns `True` if every element in a given iterable satisfies the coroutine
    asynchronous test.

    If any iteratee coroutine call returns `False`, the process is inmediately
    stopped, and `False` will be returned.

    You can increase the concurrency limit for a fast race condition scenario.

    This function is a coroutine.

    This function can be composed in a pipeline chain with ``|`` operator.

    Arguments:
        coro (coroutine function): coroutine function to call with values
            to reduce.
        iterable (iterable): an iterable collection yielding
            coroutines functions.
        limit (int): max concurrency execution limit. Use ``0`` for no limit.
        loop (asyncio.BaseEventLoop): optional event loop to use.

    Raises:
        TypeError: if input arguments are not valid.

    Returns:
        bool: `True` if all the values passes the test, otherwise `False`.

    Usage::

        async def gt_10(num):
            return num > 10

        await paco.every(gt_10, [1, 2, 3, 11])
        # => False

        await paco.every(gt_10, [11, 12, 13])
        # => True
