#### §2.3.5.(c) Problematic callin binding

A callin binding (§4) may silently fail due to a `org.objectteams.LiftingFailedException`. This exception will actually remain hidden because the callin binding is not explicitly invoked from any source code but implicitly by the runtime dispatch mechanism. To signal this situation the compiler raises an error against such callin binding.

However, the compiler should allow to configure this error and understand the warning token `"hidden-lifting-problem"` for suppressing this problem (§4.1.(b)). If the problem is ignored/suppressed and if at runtime the lifting problem occurs, triggering of the callin binding will silently fail, i.e., the program will continue in this situation as if the binding hadn't existed in the first place.
