This works now, thanks for moritz++.

$ cat RT-122746-code
macro postfix:<!!>($o) {
    quasi {
        die "Null check failed for ", $o.Str
            unless defined {{{$o}}};
        {{{$o}}}
    }
}

say 42!!;

my $cookies;
my $food = $cookies!!
masak@siddharta ~/mine/macro-grant $ perl6 RT-122746-code
42
Null check failed for $cookies
  in any  at RT-122746-code:3
  in block <unit> at RT-122746-code:12

Marking ticket as testneeded.
