will all &b refer to  the same $z ?
yes, they will

does it mean that this is legitimate 

 sub a {
     state $x;
     my $y;
     state sub b { state $z ; return $x++ + $y++ + $z++ ; }
     return &b;   # is a \ before &b needed?

No, since you can't refer to $y in that sub (perl 5 actually allows you to 
do that but gives a warning 'Variable "%s" will not stay shared' - but I 
hope perl 6 will simply give a compile-time error)
