Temp.hs:8:2:
    Warning: This binding for `name' shadows an existing binding
             In the definition of `h'

The problem is that this warning talks only about h, and the location of h (line 8). It doesn't mention that name is also a record selector, or where its defined. My particular instance of this bug involved the data declaration being in a separate module, in code contributed by someone else that I hadn't written.

Suggestion: mention one of "its a record field name", "its from Data", "its defined on line x, in file y"
