sprintf should raise error when the number of arguments does not match the number of format specifiers

sprintf with correct number of format specifiers, arguments
>> sprintf('%s', 'hello')
=> "hello"

sprintf with a single format specifier and two arguments
>> sprintf('%s', 'hello', 'world!')
=> "hello"

sprintf with three format specifiers and two arguments
>> sprintf('%s-%s-%s', 'hello', 'world!')
ArgumentError: too few arguments
        from (irb):3:in `sprintf'
        from (irb):3
        from /home/chaitanyav/development/tools_64/bin/irb:12:in `<main>'
