expectation

The following compiles fine (dependencies -> dependenciez):

case class Project(name: String)
def (name: String) dependencies = ???
def (project: Project) dependenciez = project.name.dependencies

So the original code should also compile.

Possibly related: #7375, #7401.

It does not find the member because there is a cyclic reference, since dependencies does not have a result type.
