Sick... and... wrong. :-)
Not only would it mess with what things have to do in void context, it
would fudge up the garbage collector to no end. You'd have objects
lying around in @STACK, where no sane programmer would ever use them,
and be wondering why their DESTROY hasn't been called yet.
To boot, I can't think of a way to implement that in currently-defined
Perl 6, which should scare you.
So, yeah, no, Perl 6 won't be doing that.
But if you don't mind being a little more explicit, this is nice and
easy:
our @STACK;
sub p ([EMAIL PROTECTED]) { push @STACK, @args }
p 1;
$_ = 'foo bar baz';
p split;
# @STACK is now (1, <<foo bar baz>>);
