     The lambda function - one of the foundations of functional programming -
     defines an anonymous proc and returns it. This is useful if you quickly
     need an auxiliary function for a small task.

     Although lambda defines a proc and therefore consumes memory, executing
     the same lambda expression twice will just re-define this proc.
     Thus, there is no memory leak, if you have a lambda inside a loop.
