GHC Warning Request

[Ashley Yakeley]

When -fwarn-unused-imports is switched on, "import M()" should not issue 
a warning. In 6.2, it does.

The idea is that I only wish to import instance declarations here, and 
that's the obvious way of making that explicit. I'm using -Werror (new 
in 6.2, thanks), and most of the time I'm interested in knowing about 
superfluous imports.
