Hi Gabriel, Thank you for posting those examples. Indeed, it looks like your usage of yield doesn't seem to work with jOOQ - although I must say I'm not too fluent in Scala... In any case, we do have a couple of "mismatches" because of having method names / package names, etc. that conflict with assumptions made by the Scala language. I guess that's simply inevitable...
