my problem with Moose is that its documentation becomes obsolete as time passes by and it is spread(presentations,articles,cookbooks,cpan docs) all over the internet

I disagree, if it is not in the CPAN Moose docs, then it is here, and if it not in either of those place then I don't know about it and so can't link to it. Also I am not sure how the spread and growth of information on something causes the core docs to become obsolete? If anything the core docs should always be thought of as definitive.

noone seems to understand that for it to be attractive for developers it needs to have nicely binded documentation in one place and one place only.

Actually, we understand that all to well, but it is a matter of people finding time. Personally i think the recently re-organized cookbooks as well as the new Moose::Intro and Moose::Unsweetened docs go a long way towards filling some of the needs you describe.

Of course documentation always needs work, both keeping it up to date and expanding on things which are not covered as well as they could be. You simply have to stop by #moose or ask on moose@perl.org and we will be happy to give you a commit bit and you can start fixing it right away.

as a sidenote: if I want to learn c++ it doesn't require me to understand the internals and/or read it's source code(altough on some occasions it is useful)I just need to read the description of what each class does,it's methods,some examples and I can start using it

This is not in any way a fair comparison.

C++ is over 20 years old (1985 or so) has the support of several major corporations (AT&T, IBM, Microsoft, etc), is an ANSI and ISO standard and got millions of dollars pumped into training, books and other forms of documentation over the last 15-20 years.

Moose is just 2 1/2 years old and is a volunteer driven open source project with absolutely no funding, grants or anything of the like.
