Defined in:

re.c

#==(object) ⇒ Boolean

Returns true if object is another Regexp whose pattern, flags, and encoding are the same as self, false otherwise:

/foo/ == Regexp.new('foo')                          # => true
/foo/ == /foo/i                                     # => false
/foo/ == Regexp.new('food')                         # => false
/foo/ == Regexp.new("abc".force_encoding("euc-jp")) # => false
