-class Symbol
-  # Turns the symbol into a simple proc, which is especially useful for enumerations. Examples:
-  #
-  #   # The same as people.collect { |p| p.name }
-  #   people.collect(&:name)
-  #
-  #   # The same as people.select { |p| p.manager? }.collect { |p| p.salary }
-  #   people.select(&:manager?).collect(&:salary)
-  #
-  # This is a builtin method in Ruby 1.8.7 and later.
