MiMa is telling me this:

```
[error]  * method ::()scalaz.typelevel.package#HCons# in trait scalaz.syntax.typelevel.HLists does not have a correspondent in new version
[error]    filter with: ProblemFilters.exclude[MissingMethodProblem]("scalaz.syntax.typelevel.HLists.::")
[error]  * synthetic method scalaz$syntax$typelevel$HLists$_setter_$::_=(scalaz.typelevel.package#HCons#)Unit in trait scalaz.syntax.typelevel.HLists does not have a correspondent in old version
[error]    filter with: ProblemFilters.exclude[MissingMethodProblem]("scalaz.syntax.typelevel.HLists.scalaz$syntax$typelevel$HLists$_setter_$::_=")
```

Can this be ignored?
