Re^4: 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.

(5).foo();

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;
