Comment:
I have documented the new `:info!` functionality. Just for future
documentation, here is an example of the use case for this feature:
In scope:
{{{
Accessor
Applicateive
instance Monoid Int
instance Monoid m => Applicative (Accessor m)
}}}
Not in scope:
{{{
Monoid
}}}
With this setup, we can use the instance for `Applicateive (Accessor Int)`
even though the name `Monoid` is not in scope, but `:info` will not show
the relevant instance.
