overloadedrecfldsfail06.hs:7:1: error: [-Wunused-imports (in -Wextra), Werror=unused-imports]
The import of ‘Unused(unused), V(x), U(y), MkV, Unused’
from module ‘OverloadedRecFldsFail06_A’ is redundant
overloadedrecfldsfail06.hs:8:1: error: [-Wunused-imports (in -Wextra), Werror=unused-imports]
The qualified import of ‘OverloadedRecFldsFail06_A’ is redundant
except perhaps to import instances from ‘OverloadedRecFldsFail06_A’
To import instances alone, use: import OverloadedRecFldsFail06_A()
