 What happens:

 {{{
 Prelude> :i Fish

 Top level: Not in scope: data constructor ‘Fish’
 }}}

 This is potentially confusing because `:i` can be used for type
 constructors and classes, as well as data constructors. What I think
 should happen:

 {{{
 Prelude> :i Fish

 Top level: Not in scope: constructor or class ‘Fish’
 }}}
