Obviously you can expect some models to be cyclic, like the stock affecting flow. That case should be the only possible cyclic structure, since when that is translated to stan it would represent that the atock value is equal to the previous time's state values.
This is because we need sequential evaluation in Stan; a cyclic component prevents this from working.
