Perhaps, it would make sense to add an interface for that? Also, do we need to have separate method `exceptionsInto` only for lambdas? And finally, yes, I also was thinking to have default exception handler. So, I think it will be a good idea to add this, thanks. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
