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!
Watch Your Grammar! (Score:2)
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 :)
