 If I write a list like:

 {{{other-modules: Foo.Bar.Quux, Foo.Bar.Blat, Foo.Bar.Quux}}}

 in my {{{.cabal}}} file, {{{setup configure}}} will happily accept it. But
 then when I build, GHC will give me an error message like:

 {{{
 <no location info>:
     module `blat:Foo.Bar.Quux' is defined in multiple files:
 Foo/Bar/Quux.hs
 Foo/Bar/Quux.hs
 }}}

 which is very confusing! Can Cabal check for duplicates in the exposed-
 modules and other-modules lists?
