A method/attribute to look at, in particular if this method/attribute has no documentation.
It can be a method/attribute of the superclass or of an included module, including the Kernel module, which is always appended to the included modules.
Returns nil if there is no such method/attribute. The #is_alias_for method/attribute, if any, is not included.
