Sorry for being blunt, as a matter of fact I am not, it is just the timing
of the response :(
The sooner you forget about C++ the sooner you will get Ruby.

This is a very reasonable point, it  is all about "enabeling" and
"controlling" approach.

Ruby happens to be very liberal and of course there are downs. (so comparin=
g
with C++ will give you lots of headaches I am afraifd)
 For  most of the part we - those who love ruby - think that the ups
outweight the downs.
The example you have given is not really anything unusual for the ruby
philosophy.
Look at this e.g

a =3D Object.new
class << a
    private
    def hello
        puts "Hi there"
    end
end
a.send :hello

I'm a beginner, so please let me know if I'm missing anything. Thanks
