NilClass#===

(nil) -> true

(untyped obj) -> bool

true === other → true or false

false === other → true or false

nil === other → true or false

#define case_equal rb_equal

Returns true or false.

Like Object#==, if object is an instance of Object (and not an instance of one of its many subclasses).

This method is commonly overridden by those subclasses, to provide meaningful semantics in case statements.
