Alias of #eql?
Returns true if object is another Regexp whose pattern, flags, and encoding are the same as self, false otherwise:
Example
/foo/ == Regexp.new('foo') # => true /foo/ == /foo/i # => false /foo/ == Regexp.new('food') # => false /foo/ == Regexp.new("abc".force_encoding("euc-jp")) # => false
