It would be extraordinarily useful if retrolambda spit out a warning if java.util.function.* functions or other known backwords-incompatible code is found.
This could be configurable to either not show warnings or throw errors instead, but if it warned by default I think it would stop a lot of people from running into the problem by accident and simply having the application crash at runtime, as I would imaging that pretty much every platform that you'd use retrolambda for wouldn't have java.util.function.*. Most of the time the errors that occur are pretty indecipherable unless you already know that this is a problem.
