Scala macros evaluate Enumeration values

Question

Given an Enumeration like this:

object Enum1 extends Enumeration {
  val value1, value2 = Value
  val value3 = Value("value3Name")

  val notNewAValue = value3

}

And an object like this:

@MyMacro
object MacroObject

How could I access the values of Enum1 (or any other Enumeration passed as a parameter) in the macro annotation MyMacro?

When I say "values" I'm not considering notNewAValue, only value1, value2 and value3.
