Hello,

I was wondering if it’s possible to just use `Failure()` in a Rails view and if so how to mix those modules in. Simply doing `include Dry::Monads[:result]` in the controller works for the code inside controller actions, but doesn’t seem to cascade in any way to the views. I’m getting a

```auto
NameError - uninitialized constant #<Class:0x00007f46c356cac8>::Failure:

```

failure if I do that.

I create a shortcut constant for these situations. `T` is my `Types` shortcut, `M` is my `Dry::Monads` shortcut. You could just reference `M::Failure()` as you would with the mixin method.

Side note: as I mentioned [elsewhere](https://discourse.dry-rb.org/t/conflit-using-dry-monads-and-view-component/1728/3), I don’t think using Monads in view logic is a good idea for the same reasons why using branching logic is a bad idea.
