This works with inline type classes and conditions that can be evaluated
at compile-time like `>`, `!`, and `==`:
```scala
scala> refineMV[Int, Positive1](5)
val res1: eu.timepit.refined.api.Refined[Int, eu.timepit.refined.Positive1] = 5
scala> refineMV[Int, Positive1](-5)
1 |refineMV[Int, Positive1](-5)
|^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|no
scala> refineMV[String, NonEmpty1]("hello")
val res2: eu.timepit.refined.api.Refined[String, eu.timepit.refined.NonEmpty1] = hello
scala> refineMV[String, NonEmpty1]("")
1 |refineMV[String, NonEmpty1]("")
|^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|no
