When trying to build the project that uses macro annotations, compilation fails with:
[error] splain-macro-annotations/Test.scala:7:23: macro annotation could not be expanded (you cannot use a macro annotation in the same compilation run that defines it)
[error] @newtype case class Foo(ix: Int)
[error] ^
[error] one error found
The error message is the same as if you forget to add -Ymacro-annotations compiler flag.
