Description

We had a good one in https://github.com/typelevel/feral/pull/52#issuecomment-974246880, but then I went and changed the lambda encoding in #60. So would be good to make a new one. I.e. something that works for INothing but doesn't work for vanilla Nothing, but maybe that's too ambitious :P in which case an ordinary is just fine :)

Research direction

Start by reviewing the implicit-resolution example in pull request #52 and the lambda-encoding changes in #60. Locate the existing tests for this behavior and add a regression case covering INothing; done means the test passes and, if feasible, demonstrates the contrast with vanilla Nothing.
