It is shown that the main idea of the recent study of "coherent perfect absorption" coincides with that published in 1962 by A.P. Khapalyuk. Generalization of this approach to the case of layered systems with alternating absorbing and amplifying media needs a more thorough analysis of possible instabilities.
