      Description

      One approach to using nested functions is grouping pieces of code, for instance, configuration of several views in a function called `configureViews`.

      In such task, the natural way of looking at it would be to call the functions first, as they serve as a sort of summary, and then define the functions later.

      Doing so will result in the following error being displayed:
      `Use of local variable `[functionName]` before its declaration`

      See attached Playground.
