Restricting the scope of implicits

locally.scala

// a function with non-ambiguous type signature
def justDoIt(implicit p0: Char, p1: String, p2: Int) = p0 + p1 * p2

// restrict the scope of implicits
{
  implicit val x = 3
  implicit val c = 'a'
  implicit val s = "abc"
  justDoIt // returns aabcabcabc
}

justDoIt // compilation error: could not find implicit value for parameter p2: Int
