Hi @robstoll, I'm working on issue 216. You mention that we need to implement _resolve using ExpectImpl.feature.f1. Do you have an example that could help me with this implementation? The closest example I found was _parent, and it uses ExpectImpl.feature.extractor. Thanks!

it's a simplified ExpectImpl.feature.extractor, you only need to pass the

Expect

, a function reference and the argument and get immediately an ExtractedFeaturePostStep
