X-Git-Tag: 0.0.5~1 X-Git-Url: http://gitweb.michael.orlitzky.com/?a=commitdiff_plain;h=2924d6a843aa0d4a0d9612a5d2e1e1203931302e;hp=2924d6a843aa0d4a0d9612a5d2e1e1203931302e;p=mailbox-count.git src/OptionalConfiguration.hs: import (<>) from the Semigroup class. Ha ha, although Data.Semigroup was moved into GHC in v8.0, it wasn't added to Prelude until v8.4. So there's a THIRD distinct situation we need to handle to define a friggin monoid. ---
