i made this lib back in the ghc 6.4 days, so it probably have a lot of compatibility problems here and there :( i'm self still use ghc 6.6 :)
When I try to build ArrayRef 0.1.3 I get:
Control/Concurrent/LockingBZ.hs:159:54: Ambiguous type variable `e' in the constraint: `Exception e' arising from a use of `throw' at Control/Concurrent/LockingBZ.hs:159:54-60 Probable fix: add a type signature that fixes these type variable(s)
It needs --constraint='base<4' when compiling. Here, with cabal and ghc 6.10: $ cabal install --constraint='base<4' arrayref Resolving dependencies... Downloading ArrayRef-0.1.3...
