You can hook D's assert and do what you want with it.
With the caveat that you must finish by either exiting the app or throwing an exception, since the compiler doesn't generate a stack frame that can be returned from.
Exceptions are meant for RECOVERABLE errors. If you're using them instead of assert for logic bugs, you're looking at undefined behavior. Logic bugs are not recoverable.
In a multithreaded program, does this mean that the thread must be terminated or the entire process? In a multi-user system, does this mean the transaction or the entire process? The scope of a logic bug can be known to be quite limited. Remember my earlier point about Erlang, where a "process" there is actually just a logical thread in the VM.
