# <!-- rdoc-file=object.c -->
# Object is the default root of all Ruby objects.  Object inherits from
# BasicObject which allows creating alternate object hierarchies.  Methods on
# Object are available to all classes unless explicitly overridden.
#
# Object mixes in the Kernel module, making the built-in kernel functions
# globally accessible.  Although the instance methods of Object are defined by
# the Kernel module, we have chosen to document them here for clarity.
#
# When referencing constants in classes inheriting from Object you do not need
# to use the full namespace.  For example, referencing `File` inside `YourClass`
# will find the top-level File class.
#
# In the descriptions of Object's methods, the parameter *symbol* refers to a
# symbol, which is either a quoted string or a Symbol (such as `:name`).
#
# ## What's Here
#
# First, what's elsewhere. Class Object:
#
# *   Inherits from [class BasicObject](rdoc-ref:BasicObject@What-27s+Here).
# *   Includes [module Kernel](rdoc-ref:Kernel@What-27s+Here).
#
# Here, class Object provides methods for:
#
# *   [Querying](rdoc-ref:Object@Querying)
# *   [Instance Variables](rdoc-ref:Object@Instance+Variables)
# *   [Other](rdoc-ref:Object@Other)
#
# ### Querying
#
# *   #!~: Returns `true` if `self` does not match the given object, otherwise
#     `false`.
# *   #<=>: Returns 0 if `self` and the given object `object` are the same
#     object, or if `self == object`; otherwise returns `nil`.
# *   #===: Implements case equality, effectively the same as calling #==.
# *   #eql?: Implements hash equality, effectively the same as calling #==.
# *   #kind_of? (aliased as #is_a?): Returns whether given argument is an
#     ancestor of the singleton class of `self`.
# *   #instance_of?: Returns whether `self` is an instance of the given class.
# *   #instance_variable_defined?: Returns whether the given instance variable
#     is defined in `self`.
# *   #method: Returns the Method object for the given method in `self`.
# *   #methods: Returns an array of symbol names of public and protected methods
#     in `self`.
# *   #nil?: Returns `false`. (Only `nil` responds `true` to method `nil?`.)
# *   #object_id: Returns an integer corresponding to `self` that is unique for
#     the current process
# *   #private_methods: Returns an array of the symbol names of the private
#     methods in `self`.
# *   #protected_methods: Returns an array of the symbol names of the protected
#     methods in `self`.
# *   #public_method: Returns the Method object for the given public method in
#     `self`.
# *   #public_methods: Returns an array of the symbol names of the public
#     methods in `self`.
# *   #respond_to?: Returns whether `self` responds to the given method.
# *   #singleton_class: Returns the singleton class of `self`.
# *   #singleton_method: Returns the Method object for the given singleton
#     method in `self`.
# *   #singleton_methods: Returns an array of the symbol names of the singleton
#     methods in `self`.
#
# *   #define_singleton_method: Defines a singleton method in `self` for the
#     given symbol method-name and block or proc.
# *   #extend: Includes the given modules in the singleton class of `self`.
# *   #public_send: Calls the given public method in `self` with the given
#     argument.
# *   #send: Calls the given method in `self` with the given argument.
#
# ### Instance Variables
#
# *   #instance_variable_get: Returns the value of the given instance variable
#     in `self`, or `nil` if the instance variable is not set.
# *   #instance_variable_set: Sets the value of the given instance variable in
#     `self` to the given object.
# *   #instance_variables: Returns an array of the symbol names of the instance
#     variables in `self`.
# *   #remove_instance_variable: Removes the named instance variable from
#     `self`.
#
# ### Other
#
# *   #clone:  Returns a shallow copy of `self`, including singleton class and
#     frozen state.
# *   #define_singleton_method: Defines a singleton method in `self` for the
#     given symbol method-name and block or proc.
# *   #display: Prints `self` to the given IO stream or `$stdout`.
# *   #dup: Returns a shallow unfrozen copy of `self`.
# *   #enum_for (aliased as #to_enum): Returns an Enumerator for `self` using
#     the using the given method, arguments, and block.
# *   #extend: Includes the given modules in the singleton class of `self`.
# *   #freeze: Prevents further modifications to `self`.
# *   #hash: Returns the integer hash value for `self`.
# *   #inspect: Returns a human-readable  string representation of `self`.
# *   #itself: Returns `self`.
# *   #method_missing: Method called when an undefined method is called on
#     `self`.
# *   #public_send: Calls the given public method in `self` with the given
#     argument.
# *   #send: Calls the given method in `self` with the given argument.
# *   #to_s: Returns a string representation of `self`.
