UnboundMethod
ruby/spec describes 21 methods in core/unboundmethod, and Metorex implements 14 of them. The parameters are what Method#parameters answers under Metorex.
UnboundMethod#==: implemented, parameters[[:req]]. Two unbound method objects are equal if they refer to the same method definition.UnboundMethod#arity: implemented, parameters[]. Returns an indication of the number of arguments accepted by a method. An example calling it.UnboundMethod#bind: not implemented. Bind umeth to obj. An example calling it.UnboundMethod#bind_call: not implemented. Bind umeth to recv and then invokes the method with the specified arguments. An example calling it.UnboundMethod#clone: implemented, parameters[]. Returns a clone of this method. An example calling it.UnboundMethod#dup: implemented, parameters[]. Produces a shallow copy of obj---the instance variables of obj are copied, but not the objects they reference. An example calling it.UnboundMethod#eql?: implemented, parameters[[:req]]. Two unbound method objects are equal if they refer to the same method definition. An example calling it.UnboundMethod#hash: implemented, parameters[]. Returns a hash value corresponding to the method object. An example calling it.UnboundMethod#inspect: implemented, parameters[]. Returns a human-readable description of the underlying method. An example calling it.UnboundMethod#name: implemented, parameters[]. Returns the name of the method. An example calling it.UnboundMethod#original_name: implemented, parameters[]. Returns the original name of the method. An example calling it.UnboundMethod#owner: implemented, parameters[]. Returns the class or module on which this method is defined. An example calling it.UnboundMethod#parameters: implemented, parameters[]. Returns the parameter information of this method. An example calling it.UnboundMethod#private?: not implemented.UnboundMethod#protected?: not implemented.UnboundMethod#public?: not implemented.UnboundMethod#source_location: implemented, parameters[]. Returns the location where the method was defined. An example calling it.UnboundMethod#source_range: not implemented.UnboundMethod#super_method: implemented, parameters[]. Returns aMethodof superclass which would be called when super is used or nil if there is no method on superclass. An example calling it.UnboundMethod#syntax_tree: not implemented.UnboundMethod#to_s: implemented, parameters[]. Returns a human-readable description of the underlying method. An example calling it.
