Expectation

This is what you get in Scala 2 at typer

FooMacros.scala:2: error: macro definition needs to be enabled
by making the implicit value scala.language.experimental.macros visible.
This can be achieved by adding the import clause 'import scala.language.experimental.macros'
or by setting the compiler option -language:experimental.macros.
See the Scaladoc for value scala.language.experimental.macros for a discussion
why the feature needs to be explicitly enabled.
  def foo: String = macro Foo.fooImpl[T]
      ^
