Hm, it's completely mysterious to me why we get the compiler warning in the first place -- shouldn't "M" just be equivalent to 'M':[], as far as GHC is concerned? But this does fix it. Could I ask you to clean up your commit message, though? First line should just be a brief description of the change.
