Can you supply a reference to this article. I'm assuming you mean either of Larry's Apocalypses or Damian's Exegesis, but the nearest I can find is this from Apocalypse 2

Various special punctuation variables are gone in Perl 6, including all the deprecated ones.

And I find it a difficult leap from there to "Most special variables are being removed from Perl 6". Especially when Larry goes on to say:

(Non-deprecated variables will be replaced by some kind of similar functionality that is likely to be invoked through some kind of method call on the appropriate object. If there is no appropriate object, then a named global variable might provide similar functionality.)
