Moose is an extension of the Perl 5 object system.
-=head2 Another object system!?!?
-
-Yes, I know there has been an explosion recently of new ways to
-build object's in Perl 5, most of them based on inside-out objects
-and other such things. Moose is different because it is not a new
-object system for Perl 5, but instead an extension of the existing
-object system.
-
-Moose is built on top of L<Class::MOP>, which is a metaclass system
-for Perl 5. This means that Moose not only makes building normal
-Perl 5 objects better, but it also provides the power of metaclass
-programming.
-
-=head2 Is this for real? Or is this just an experiment?
-
-Moose is I<based> on the prototypes and experiments I did for the Perl 6
-meta-model. However, Moose is B<NOT> an experiment/prototype; it is for B<real>.
-
-=head2 Is this ready for use in production?
-
-Yes, I believe that it is.
-
-Moose has been used successfully in production environemnts by several people
-and companies (including the one I work for). There are Moose applications
-which have been in production with little or no issue now for well over a year.
-I consider it highly stable and we are commited to keeping it stable.
-
-Of course, in the end, you need to make this call yourself. If you have
-any questions or concerns, please feel free to email me, or even the list
-or just stop by #moose and ask away.
+The main goal of Moose is to make Perl 5 Object Oriented programming
+easier, more consistent and less tedious. With Moose you can to think
+more about what you want to do and less about the mechanics of OOP.
-=head2 Is Moose just Perl 6 in Perl 5?
-
-No. While Moose is very much inspired by Perl 6, it is not itself Perl 6.
-Instead, it is an OO system for Perl 5. I built Moose because I was tired of
-writing the same old boring Perl 5 OO code, and drooling over Perl 6 OO. So
-instead of switching to Ruby, I wrote Moose :)
-
-=head2 Wait, I<post> modern, I thought it was just I<modern>?
-
-So I was reading Larry Wall's talk from the 1999 Linux World entitled
-"Perl, the first postmodern computer language" in which he talks about how
-he picked the features for Perl because he thought they were cool and he
-threw out the ones that he thought sucked. This got me thinking about how
-we have done the same thing in Moose. For Moose, we have "borrowed" features
-from Perl 6, CLOS (LISP), Smalltalk, Java, BETA, OCaml, Ruby and more, and
-the bits we didn't like (cause they sucked) we tossed aside. So for this
-reason (and a few others) I have re-dubbed Moose a I<postmodern> object system.

+=head1 FEATURE REQUESTS
+
+We are very strict about what features we add to the Moose core, especially
+the user-visible features. Instead we have made sure that the underlying
+meta-system of Moose is as extensible as possible so that you can add your
+own features easily. That said, occasionally there is a feature needed in the
+meta-system to support your planned extension, in which case you should
+either email the mailing list or join us on irc at #moose to discuss.
