That's a little disingenuous. Not really. It just shows that feature-completeness may be a good metric when comparing implementations of the same language, but

That's a little disingenuous. Not really. It just shows that feature-completeness may be a good metric when comparing implementations of the same language, but not so much when comparing them to implementations of a different language. the fact that someone wrote a Tetris clone in one of multiple incomplete implementations of Perl 6 doesn't mean that Perl 6 is actually useful for much The fact that there's a Tetris-clone in Perl6 indeed doesn't mean much. However, the fact that it uses GTK is an example of CLR interop, which opens up a whole new level of practical applicability.
