Edward
Can you perhaps bring the core libraries committee to consensus on this (I think minor) issue, and we can then get on with implementing it?
Many thanks -- hope to se you at ICFP.

| Comment (by RyanGlScott):
|
| To follow up on my proposed experiment (in comment:29), I built about
| 143
| commonly used Hackage libraries using the `wip/T13064` GHC branch. Of
| those 143, I noticed new warnings being emitted in 31 of them (~22%):
|
| {{{
| - adjunctions-4.4
| - aeson-1.4.0.0
| - ansi-wl-pprint-0.6.8.2
| - asn1-encoding-0.9.5
| - async-2.2.1
| - attoparsec-0.13.2.2
| - blaze-builder-0.4.1.0
| - cassava-0.5.1.0
| - conduit-1.3.0.3
| - cookie-0.4.4
| - foundation-0.0.21
| - Glob-0.9.2
| - haskell-src-exts-1.20.2
| - hspec-core-2.5.6
| - lens-4.17
| - math-functions-0.3.0.2
| - memory-0.14.16
| - microstache-1.0.1.1
| - mono-traversable-1.0.9.0
| - network-2.8.0.0
| - primitive-0.6.4.0
| - resourcet-1.2.1
| - scientific-0.3.6.2
| - tasty-1.1.0.3
| - th-orphans-0.13.6
| - unordered-containers-0.2.9.0
| - uuid-types-1.0.3
| - x509-1.7.4
| - x509-store-1.6.6
| - x509-system-1.6.6
| - yaml-0.10.1.1
| }}}
|
| I still advocate adopting this change, but it is worth noting that a
| non-
| trivial number of existing libraries will need to be updated in order
| to
| accommodate the new warnings.
