A question, you say that you do not think Parrot will ever run a real-world language but then mainly go on to explain why this is the case for Python, and unless I've misunderstood the reason you give is that Parrot does not fit well with the internal Python workings. From what I've seen on the perl6 and parrot mailing lists (mind you, I only understand about 1/10th of what goes on there, so I may be wrong) development of Parrot is mainly directed towards serving as a VM for Perl 6. I know cross-language compatibility is one of the project goals and often expounded as one of the main selling points, but at the moment the project seems to be headed towards getting Perl 6 running first and worry about the others later.
Also (again, unless I'm misunderstanding something) Pugs is beginning to target Parrot as a backend, as is PGE, so some real work seems to be going on to establish Parrot as the working VM.
Do you think the plan of action of getting Perl 6 running first and then "fix" the VM towards suitability for other languages gradually is infeasible? Will it be stuck in too many ruts to ever serve as a general-purpose VM for dynamic languages? Personally I couldn't care less about Python running on Parrot, my main interest would be in Perl 6.
Or was your main point that you do not see Parrot ever evolving to a state of usefulness because of the people who are currently working on it and the personal politics involved (you've certainly not been the first to express that POV)?
