7.  macro def assert(assertion: Assertion[Boolean]): QuotedAssertion[Boolean]

   This method is used to generate Newtype that can be validated at compile-time.

   This method is used to generate Newtype that can be validated at compile-time. This must wrap a Assertion and be assigned to def assertion.

   For example, here is a refined Newtype for Natural numbers. Natural numbers are whole numbers greater than or equal to 0.

   import zio.prelude.Subtype
   import zio.prelude.Assertion._
   
   type Natural = Natural.Type
   object Natural extends Subtype[Int] {
     def assertion = assert(greaterThanOrEqualTo(0))
   }

   With this assertion defined, Natural.apply will check literal values at compile-time, failing with an error message if the Assertion is not satisfied.

   Natural(-10) would render "-10 failed to satisfy greaterThanOrEqualTo(10)"

   IMPORTANT: Due to the macro machinery powering this feature, you must be sure to NOT ANNOTATE def assertion with a type (QuotedAssertion). If you do so, the macro will not be able to run the provided assertion at compile-time and will fail with a message containing this very same information.

8.  macro def assertCustom(f: (Boolean) => Either[AssertionError, Unit]): QuotedAssertion[Boolean]

   This method is used as an escape hatch for assert to allow Newtypes to use custom functions.

   This method is used as an escape hatch for assert to allow Newtypes to use custom functions. If at all possible, you should use assert instead.

   This will use whitebox.Context.eval under the hood, so all limitations of that function apply here. See here for details: https://github.com/scala/scala/blob/2.13.x/src/reflect/scala/reflect/macros/Evals.scala#L69
