in thread I dislike object-oriented programming in general

The reason why that doesn't work is a legacy error in the ECMAScript standard. By following a numeral with a dot, the parser expects that you're defining a floating-point value, rather than an integer. You can still call methods on it, however, if you disambiguate by wrapping it in parentheses first.

    Ah. That makes perfect sense.

    When you put it that way, I'm a little surprised that Ruby correctly understands this: 

    class Fixnum;
  def hello ()
    puts 'hi';
  end;
end;

5.hello;
