I was playing with a couple of simple overload-protection current limiters, and expected to need to add loop compensations. To my surprise, both were stable. They would of course usually not run in current limit; the opamps would normally be railed and the fets low-ohmic. So a little oscillation wouldn't be a show-stopper. But still.
