{{{

6:
7: h :: a -> a
8: h name = name
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"
