A Quick and Dirty Lens primer

Why does Lens exist? Well, Haskell records suck, for a number of reasons. I will enumerate them using this sample record.

data User = User { login    :: Text
                 , password :: ByteString
                 , email    :: Text
                 , created  :: UTCTime
 }

trait Show[A]

// These formulations all compile.
class A {
  implicit def z1[A]: Show[A] = null
  def f[A](implicit z: Show[A]): String = null

  f
  f[Int]
  f[Int](implicitly)
