I wrote my first Perl6 program last night, using the Rakudo implementation on the Parrot virtual machine. Compilation is slow, but runtime is fast. I made a lot of mistakes, and the compiler doesn't print very useful syntax error messages yet, but once I figured out a few gotchas (like you can't have a grammar rule named "null", that must be reserved somewhere) it worked and all of my tests passed.
Take that, false vaporware accusers!
Or better yet, let us watch your grammar. I'm sure we'd love to see examples of it.
I've been playing with it myself and so far I'm quite happy
