| Hi SPJ,
| 
| it seems as if your latest commit

| broke the build (when building with -Werror and -dcore-lint):
| 
| libraries/array/Data/Array/Base.hs:476:1: Warning:
|     Forall'd constraint ‘Ix i’ is not bound in RULE lhs
|       showsIArray
|         @ UArray @ i @ e $dIArray_a4L0 $dIx_a4L9 $dShow_a4L2 $dShow_a4L3
| 
| <no location info>:
| Failing due to -Werror.
| make[1]: *** [libraries/array/dist-install/build/Data/Array/Base.o]
