This is a Ruby tree! It shows every object from the Ruby Programming Language in a tree format.
# Set.member? (from ruby core) --- member?(o) --- (This method is an alias for Set#include?.) Returns true if the set contains the given object. Note that `include?` and `member?` do not test member equality using `==` as do other Enumerables. See also Enumerable#include?
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.
