There’s your problem:

... if some one asks you if they can simply go and use Perl 6 for all things they use Perl 5 today, Your answer will be a straight 'No.'

“Therefore, it is not ‘Perl-6.’”   Period, hard-stop, end-of-sentence.   I don’t know what it is (and at this point I frankly do not find reason to care), but the bottom line is that you are creating:   a different language.   Stack it alongside, say, Haskell or Lustre or Simple or Sartre or Brainf*ck or InterCal or Piet or Whitespace, and hope for the best.   But, please, don’t play out in real-life the old joke about the woman who was married to an IBM salesman for thirty years but was still a virgin ... “all he did was to sit on the edge of the bed and tell me how good it was going to be.”   :-)
