There is also the situation where the package name isn’t essential and<br>
shouldn’t get in the way when naming modules. For example, there are a<br>
lot of monad transformers in the world. The `transformers` package<br>
implements some of them; others are added by other packages. It is good<br>
if the module that implements a certain kind of monad transformer has a<br>
name of the form `Control.Monad.Trans.⟨type-of-transformer⟩`. Having the<br>
package name in the module name would be like revealing an<br>
implementation detail.<br>

All the best,<br>
