Yes. Suppose you change the deps: hunk ./plugins.cabal 42 - Cabal >= 1.4 && < 1.5, + Cabal >= 1.4, And then try to compile, you'll see (at least for me): [ 3 of 16] Compiling System.Plugins.ParsePkgConfCabal ( src/System/Plugins/ParsePkgConfCabal.hs, dist/build/System/Plugins/ParsePkgConfCabal.o ) src/System/Plugins/ParsePkgConfCabal.hs:287:34: Ambiguous occurrence `depends' It could refer to either `Distribution.InstalledPackageInfo.depends', imported from Distribution.InstalledPackageInfo at src/System/Plugins/ParsePkgConfCabal.hs:8:0-39 or `Distribution.Package.depends', imported from Distribution.Package at src/System/Plugins/ParsePkgConfCabal.hs:9:0-26 src/System/Plugins/ParsePkgConfCabal.hs:300:36: Ambiguous occurrence `depends' It could refer to either `Distribution.InstalledPackageInfo.depends', imported from Distribution.InstalledPackageInfo at src/System/Plugins/ParsePkgConfCabal.hs:8:0-39 or `Distribution.Package.depends', imported from Distribution.Package at src/System/Plugins/ParsePkgConfCabal.hs:9:0-26 -- gwern
