Hi @malonehedges, this is a bug in the compiler unfortunately. We have it documented in TCA, but perhaps we need to document it in this repo too:

https://pointfreeco.github.io/swift-composable-architecture/main/documentation/composablearchitecture/reducer()#Circular-reference-errors

As this is not an issue with the library I am going to convert it to a discussion.
