> The `ContextChecker` is a little component in the compiler that checks if all inputs
are set in the different contracts.
> It seems that the checker is currently not called at all, so weird exceptions from the
compiler occur if one forgot to set an input.
> It also seems that the Checker hasn't been implemented very well and it also has not
been maintained, so it is probably not compatible to the Iterations.
> So we need to rework the code, add testcases for it and integrate it properly into the
compilation process.
> I noticed the bug by creating a `GenericDataSink` without any inputs.
