I don't think that we can really consider Perl 6 and Parrot to be anything but abysmal failures at this point. The people developing and advocating for them have had many years now to product something that's even minimally usable, and we just haven't seen that happen.

Writing traditional compilers and interpreters, or emitting C, or targeting LLVM have all proven to be good ways of getting production-grade programming language implementations created and usable quickly. Messing around with Parrot has never resulted in anything useful.
