# A Module is a collection of methods and constants. The methods in a module may
# be instance methods or module methods. Instance methods appear as methods in a
# class when the module is included, module methods do not. Conversely, module
# methods may be called without creating an encapsulating object, while instance
# methods may not. (See Module#module_function.)
#
# In the descriptions that follow, the parameter *sym* refers to a symbol, which
# is either a quoted string or a Symbol (such as `:name`).
#
# module Mod
# include Math
# CONST = 1
# def meth
# # ...
# end
# end
# Mod.class #=> Module
# Mod.constants #=> [:CONST, :PI, :E]
# Mod.instance_methods #=> [:meth]
#
class Module < Object
 # In the first form, returns an array of the names of all constants accessible
 # from the point of call. This list includes the names of all modules and
 # classes defined in the global scope.
 #
 # Module.constants.first(4)
 # # => [:ARGF, :ARGV, :ArgumentError, :Array]
 #
 # Module.constants.include?(:SEEK_SET) # => false
 #
 # class IO
 # Module.constants.include?(:SEEK_SET) # => true
 # end
 #
 # The second form calls the instance method `constants`.
 #
 def self.constants: () -> ::Array[Integer]

# Returns the list of `Modules` nested at the point of call.
  #

  #       module M2

  #
  def self.used_modules: () -> ::Array[Module]

# Returns true if *mod* is a subclass of *other*. Returns `nil` if there's no
 # relationship between the two. (Think of the relationship in terms of the class
 # definition: "class A < B" implies "A < B".)
 #
 def <: (Module other) -> bool?

# Returns true if *mod* is a subclass of *other* or is the same as *other*.
 # Returns `nil` if there's no relationship between the two. (Think of the
 # relationship in terms of the class definition: "class A < B" implies "A < B".)
 #
 def <=: (Module other) -> bool?

# Comparison---Returns -1, 0, +1 or nil depending on whether `module` includes
 # `other_module`, they are the same, or if `module` is included by
 # `other_module`.
 #
 # Returns `nil` if `module` has no relationship with `other_module`, if
 # `other_module` is not a module, or if the two values are incomparable.
 #
 def <=>: (Module other) -> Integer?

# Equality --- At the Object level, #== returns `true` only if `obj` and `other`
  # are the same object.  Typically, this method is overridden in descendant
  # classes to provide class-specific meaning.
  #
  # Unlike #==, the #equal? method should never be overridden by subclasses as it
  # is used to determine object identity (that is, `a.equal?(b)` if and only if
  # `a` is the same object as `b`):
  #
  #     obj = "a"
  #     other = obj.dup
  #
  #     obj == other      #=> true
  #     obj.equal? other  #=> false
  #     obj.equal? obj    #=> true
  #
  # The #eql? method returns `true` if `obj` and `other` refer to the same hash
  # key.  This is used by Hash to test members for equality.  For any pair of
  # objects where #eql? returns `true`, the #hash value of both objects must be
  # equal. So any subclass that overrides #eql? should also override #hash
  # appropriately.
  #
  # For objects of class Object, #eql?  is synonymous with #==.  Subclasses
  # normally continue this tradition by aliasing #eql? to their overridden #==
  # method, but there are exceptions. Numeric types, for example, perform type
  # conversion across #==, but not across #eql?, so:
  #
  #     1 == 1.0     #=> true
  #     1.eql? 1.0   #=> false
  #
  def ==: (untyped other) -> bool

# Case Equality---Returns `true` if *obj* is an instance of *mod* or an instance
  # of one of *mod*'s descendants. Of limited use for modules, but can be used in
  # `case` statements to classify objects by class.
  #
  def ===: (untyped other) -> bool

# Returns true if *mod* is an ancestor of *other*. Returns `nil` if there's no
 # relationship between the two. (Think of the relationship in terms of the class
 # definition: "class A < B" implies "B > A".)
 #
 def >: (Module other) -> bool?

# Returns true if *mod* is an ancestor of *other*, or the two modules are the
 # same. Returns `nil` if there's no relationship between the two. (Think of the
 # relationship in terms of the class definition: "class A < B" implies "B > A".)
 #
 def >=: (Module other) -> bool?

# Makes *new_name* a new copy of the method *old_name*. This can be used to
  # retain access to methods that are overridden.
