Re^2: RFC: Is there more to alias? (perl6)

[tye]

Heh, I wonder if I'm missing something, but it appears that Data::Alias's interface is better in several ways than Perl6's. How will Perl6 support the following tasks other than with these relatively ugly hacks:

$w = alias [$x, $y, $z];
# vs.
$w[0] := $x;
$w[1] := $y;
$w[2] := $z;

alias push @x, $y;
# vs.
push @x, 0;
@x[-1] := $y;

alias my( @x )= @y;
# vs.
@x= ();
@x[$_] := @y[$_]  for 0 .. @y.last;

alias my( @x )= GetList();
# vs.
is this possible with Perl6's syntax?

Perhaps Perl6 should have 'alias' built in along with the more succinct := operator?

[Aristotle]

The following might work, and if so would cover several of the cases:

push @x, my $x := $_ for @y;

But that's still much clumsier than Data::Alias.

I have a hunch though that in Perl6 we'll be using the splat to do this, something remotely looking like

*@x := *@y;

Don't ask me about the precise syntax though.
