in reply to My own "why I like Ruby" list
in thread Other programming language I most often use

It is truly an object oriented language... no hybrid datatypes!
When I gave it a glance a while back, it didn't look like you could subclass or extend the built-in classes. Did I read that wrong?

Or am I just confusing it with that so-called OO language being hyped by Sun? {grin}

    The following code will output Ruby is a great language!
    a="Perl" def a.+ other "Ruby"+other end a+=" is a great language!\n"
    So, ruby does actually allow you to extend and redefine it's built-classes.. the example also works if you define a new class which inherits String, instead of using singleton style inheritance.. I have not however tested this with every built-in class, but those I have tried it with, worked fine!

    He he... probably... I have had alot of beginners getting really confused over the hybrid style of Java...
      Having looked at it recently I think that there may be a couple of exceptions. Specifically Fixnum. However since that is just an internal representation of Integer I don't think there is any practical limitation there.

    Heh, no, Ruby is much more dynamic than that :) You can subclass, extend, etc. to your heart's desire.
