    Hi All,

    On creation, I would like to salt some of the
    values inside an object  when the variable
    inside is an array:


    First a concept test:
    $ p6 'class AA { has Str @.I is rw; }; my $CC= AA.new; $CC.I[1] =
    "def";
    say $CC.I[1];'

    def


    Now for the pre-salt test
    $ p6 'class AA { has Str @.I is rw; }; my $CC = AA.new( I[1] =>
    "abc" );
    say $CC.I[1];'

    ===SORRY!=== Error while compiling -e
    Undeclared name:
          I used at line 1


    What am I doing wrong?

    Many thanks,
    -T

Hi Norman,

I am confused.

What I am after it pre-salting $CC.I  with
   $CC.[0] = "abc"
   $CC.[1] = "def"

with the ".new" functions when I create $CC
