Perl 6 on Parrot

"Around the time I stopped working on Parrot, people were saying that Perl 6 was going to be written in Perl 6, and I was, well, let's say, a little sceptical. But you know what? They've done it. I am astounded. It is lovely. ...

"It's really, really true. Parrot lets you implement your own languages using Perl 6 rules for the grammar and Perl 6 for the compiler."
