| 
| Lots of validate failures today (x86-64/Linux):
| 
| Unexpected failures:
|     indexed-types/should_compile         Gentle [exit code non-0]
| (normal)
|     perf/compiler                        T5030 [stat not good enough]
| (normal)
|     polykinds                            T6068 [bad stderr] (ghci)
|     rename/should_fail                   rnfail055 [stderr mismatch]
| (normal)
|     typecheck/should_compile             tc235 [exit code non-0]
| (normal)
|     typecheck/should_fail                T5684 [stderr mismatch]
| (normal)
| 
| Many of them seem to be of this kind:
| 
| +    Illegal instance declaration for `HasSingleton
| +                                        (Maybe ak) (Maybe a) mp'
| +      Multiple uses of this instance may be inconsistent
| +      with the functional dependencies of the class.
| +    In the instance declaration for `HasSingleton (Maybe a) mp'
| 
| Anyone know why this is?
| 
| Cheers,
| 	Simon
