The difference is, (AFAICT) Perl 6 also aims to be easy to use for the everyone else. Damian is extremely bright and surely wishes to have (and (I think) has helped design) a language that allows him to do some frightening and epic stuff. Larry is also a very bright guy, and is very humble, and (again, AFAICT) still requires that Perl 6 make easy things easy. "Baby Perl 6" should be easy to pick up and use.
So, the only part of the Lisp vibe I'm sensing is: yes, clever people will use Perl 6 to do clever things. But also, people who just need to get their work done in a straightforward way will be using Perl 6 as well.
My prediction: Perl 6 will have a long and steady increase in use as time goes by. This is because although there's not a tremendous amount of hype, potential users will trickle in and say, "I need to do $x"; and then as usual, Perlers will come out of the woodwork with multiple ways to quickly do $x without much trouble, and bang: you've got one more Perl 6 user.
Perl5 took off because for a lot of things it appeared to be the only game in town. Today that isn't the case anywhere. For the web there is a very established PHP (I just tried to make a web store without writing any code and I REALLY didn't want to touch PHP but there are literally no other options) and a very well established Ruby/Rails. For the enterprise you have Java, C# and all the languages that run on their respective VMs.
Perl6 has no killer app (well, I would consider Parrot potentially a killer app, but thankfully that has afaik no perl requirement). Saying "but we can get stuff done fast!" holds no water anymore. So can Ruby, Python, C#, Haskell, etc., etc., etc. It's not a selling point.
EDIT: Forgot to mention, for sys admin perl6 will be competing with, among other things perl5.
Don't get me wrong, Parrot and Perl 6 are all worthy efforts. But I'm not sure they will have the kind of impact towards growth of the language and userbase that Perl needs. Perl desperately needs better OO syntax and support for functional programming paradigms. But syntax is syntax, libraries are what make a language useful in today's day and age.
Moose though is an example of what should just be part of the language. I'm glad to hear that Perl 6 will be doing some of what I want, it'll be a good start. But Perl really really needs the kinds of things that people want to use modern languages for. It's still so geared for processing data files (of various sorts), and most of what I see in Perl 6 seems to target this problem in various ways.
Don't get me wrong, Perl is my preferred language, I can crank out a Perl solution to a problem about as fast as I can type it. But when I really want to push the project larger, the language doesn't really do much to help you.
Perl has numerous web libraries on the CPAN (Catalyst, Mojo, Dancer etc.), and if you don't like the bare-bones object system you should look at Moose.
Basically the standard Perl library are whatever functions Perl happens to have. Which, while amazing for text processing, don't help much with other needs.
A standard library, I think. Is what you go look for when you need a module to solve your problem. With Java that's [1], with Python that's [2]. With PHP (until somewhat recently) that was using one of the ~1200 built-in functions.
With Perl, the place to go for libraries is the CPAN. I look at http://search.cpan.org, not `perldoc perlmodlib` if I need a library to do X.
There are cases where this is painful, such as offline machines. But in those cases you can pack all of CPAN on a CD (with minicpan), or produce a self-contained Perl program + libraries with local::lib and/or PAR.
1. http://java.sun.com/javase/6/docs/api/ 2. http://docs.python.org/library/ 3. http://perldoc.perl.org/perlmodlib.html
EDIT: And your CD suggestion is a good way to get sacked.
Like a lot of things in working life it depends on where you're coming from and where you are but I find Perl much easier to maintain across multiple servers because of CPAN (especially by using internal mirrors... for eg. minicpan) than with some other languages.
Which is pretty much what I have to resort to :(
I don't have to do this for the most part with Java or Python.
PAR is good for deployment, but obviously hard for offline development work (sometimes you just have to do the work on those machines).
Thanks for the pointer to minicpan. I might give that a shot, might save me from manually mirroring CPAN.
Damian mentions some cool features; but I'm getting a Lisp vibe: clever people use it, they develop cool new things with it, but it doesn't attain market success (aka secret weapon). Damian himself is a clever guy (though you only hear of his over-complex stuff, the 3 he mentions, using latin, haiku and whitespace); eg. mjd too is great (http://blog.plover.com/) and of course Larry. As in Lisp, these clever ideas get adopted into other languages (eg. today, even Java has Perl-style regex).
Fitting in with this is the psychographic profile of the wish to not be standard - to do things differently - which is great (crucial) for research and development; but becoming less great for later stages, such as production code.
My personal view is that both standard and non-standard are important, though necessarily antagonistic.
