Hi Cafe.

I have written some QuickCheck properties in my source and am using these for testing, however, when I compile my program I get warned about unused imports:

...

Warning: Module `Test.QuickCheck' is imported, but nothing from it is used

Is there a way to suppress these warnings for a particular module by using a pragma directive or something similar?

You can do:

import Test.QuickCheck ()

I'm using qualified properties with (import Test.QuickCheck ((==>))) so that may not be possible.

Ah, ok. In that case you can use -fno-warn-unused-imports. You can pass that to GHC, or put it in as an OPTIONS pragma: {-# OPTIONS -fno-warn-unused-imports #-}
