Currently - and by currently I mean that only RFC 14 was adopted and
everything else stayed the same - these would have to be written as:

    @file = readline {open("</etc/motd")} or die;
    print {open(">>/var/log/logfile")} "Hello, world!";

Since an indirect object can only be a scalar, block, or bareword.
However, this is not to stop us from "fixing" this in Perl 6
necessarily, and in fact I wrote RFC 174 with this in mind. However, a
more flexible approach is not without additional problems and
ambiguities, such as these:

Tom and Damian raise some excellent points that can't be ignored if this
were to become a reality.
