# TrueClass.=== (from ruby core) --- obj === other -> true or false --- Case Equality -- For class Object, effectively the same as calling `#==`, but typically overridden by descendants to provide meaningful semantics in `case` statements.
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.
