Perl 6 has quite possibly been the biggest failure among programming languages.
You didn't read the parent post, did you? According to it, even with the backing of the DoD and commercial vendors, Ada still failed. No matter how much or how little progress Perl 6 makes, I still wouldn't give it the title of biggest failure.
