  -This is an implementation of functional references modeled as functions (in the
  -same way as transducers).

  -Functional reference or lense is a generalization of get and put mapping to the
  -particular part of a data structure, where the result is called _view_ or _focus_
  -and the container is usually called _source_.

  === First steps
  
  We'll start by using the most basic lens, the identity lens. We can get the value
  a lens is focused on using the `focus` function in `lentes.core` ns:

  ==== Conditionals
  
  And conditional lenses that can be defined using a predicate function and returns a
  lens that focuses in an element only if it passes the predicate:
