   --------------------------------------
   import java.util.List
  -#def list(List list)
  +#main (List list)
     <ul>

  Renderer call
  ~~~~~~~~~~~~~
  
  Within a renderer, another renderer can be called with the directive +#call+. The syntax is like a function call in Java.
  
  Exemple:
  --------------------------------------
  #def hello()
    Hello
    #call name("World")
  #end
  #def name(String n)
    $(n)
  #end
  --------------------------------------
  
  
negative.code: Here is the bare minimum you need to have a working template which display 'Hello World'
  
  --------------------------------------
  #main ()
    Hello World
  #end
  --------------------------------------
