It is a really nice language based off of all the tutorials and presentations I've watched. It just needs some better performance before I'll really start using it and I think there are many in the community that are in the same boat. It's a pity, because it's a chicken or the egg kind of problem. I would try to help, but when it comes to computer science I am a consumer and not a producer (I have my own large projects in my domain :)).
I'm also very impressed in how the language is turning out. It's a pleasure to write and read. I know most people really don't like Unicode operators, but I find them to be very useful. They're short and concise, and allow those writing mathematical equations to stick to their regular symbols. And for those that don't know how to do Unicode on their OS/editor, there's ASCII equivalents.
Performance-wise, it seems to be fast enough for all my personal projects, and it's getting faster every release. Is there a certain piece of code that you want to have running within a certain amount of time? That would allow you (and Perl 6 devs) to have a goal to look at, and work towards.
As a general scripting language, P6 looks nice as a lot of features such as concurrency that are aren't super straightforward (Ex: python) seem to be dead simple in P6.
In fact some things that you would do in PDL have already been added, they just currently aren't as fast as they could be.
