This is a Ruby tree! It shows every object from the Ruby Programming Language in a tree format.
# Set.to_set (from ruby core) --- to_set(klass = Set, *args, &block) --- Returns self if no arguments are given. Otherwise, converts the set to another with `klass.new(self, *args, &block)`. In subclasses, returns `klass.new(self, *args, &block)` unless overridden.
This is MURDOC! A Ruby documentation browser inspired by Smalltalk-80. It allows you to learn about Ruby by browsing through its class hierarchies, and see any of its methods.
