I have a following code:

usage.scala

object Test extends App {
   import Macros._

   val f = 1
   Macros.get(f) 
}

macros.scala

import language.experimental.macros
import scala.reflect.macros.Context

object Macros {
  def get(a: Int) = macro getImpl

  def getImpl(c: Context)(a: c.Expr[Int]) = {
    import c.universe._

     println(showRaw(a))
  }
}    

It return:

Expr(Select(This(newTypeName("Test")), newTermName("f")))

How to extract from termName("f") a 1 value ? It's possible with macros?
