Allows you to make aliases for attributes, which includes getter, setter, and a predicate.
#attr_internal

Alias for Module#attr_internal_accessor.
#attr_internal_accessor

Declares an attribute reader and writer backed by an internally-named instance variable.
#attr_internal_reader

Declares an attribute reader backed by an internally-named instance variable.
#attr_internal_writer

#cattr_accessor

Alias for Module#mattr_accessor.
#cattr_reader

Alias for Module#mattr_reader.
#cattr_writer

Alias for Module#mattr_writer.
#deep_dup

Returns a copy of module or class if it’s anonymous.
#delegate

Provides a delegate class method to easily expose contained objects’ public methods as your own.
#delegate_missing_to

#mattr_accessor

Defines both class and instance accessors for class attributes.
#mattr_reader

Defines a class attribute and creates a class and instance reader methods.
#mattr_writer

Defines a class attribute and creates a class and instance writer methods to allow assignment to the attribute.
#module_parent

Returns the module which contains this one according to its name.
#module_parent_name

Returns the name of the module containing this one.
#module_parents

Returns all the parents of this module according to its name, ordered from nested outwards.
#redefine_method

Replaces the existing method definition, if there is one, with the passed block as its body.
#redefine_singleton_method

Replaces the existing singleton method definition, if there is one, with the passed block as its body.
#remove_possible_method

Removes the named method, if it exists.
#remove_possible_singleton_method
