Well, yes, you're missing the fact that $*OUT is a variable in Perl 6:

    $*SAVED = $*OUT;
    local($*OUT) = fake_handle();

So you might consider that $*OUT is Perl 6's equivalent to the
currently selected output filehandle.  Note however that, like
select(), the above does not redirect stdout for subprocesses.
It only redirects methods implicitly bound to $*OUT, like C<print>.
