I hate being the one to say these things.
In no particular order:
The vaguest feeling that Perl6 syntax was entering the "clean up, clarify, rationalise and document phase" rather than the "throw it in and see if it flies" phase.
Some idea that some consideration was being given to ensure that the underpinning of the language (Parrot) will be capable of delivering the semantics of the language in something approaching real-time.
That one of those charged with specifying those unerpinnings had actually attempted to use the existing implementations of them before blythly spec'ing that the replacement should work the same way as the previous implementations.
Some signs the runtime library for Perl6 will be architected to reflect it's cross-platform aspirations by virtualisation of it's requirements, rather than taking a mid-1980s standard and then force-fitting it upon every other platform.
That the test suit of Perl6 components didn't simply bypass tests on inconvenient platforms in order to produce nice "headline" figures.
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
"Science is about questioning the status quo. Questioning authority".
The "good enough" maybe good enough for the now, and perfection maybe unobtainable, but that should not preclude us from striving for perfection, when time, circumstance or desire allow.
