Good points, thank you. I suppose if I really want to confuse people (again, pretty darned close to Perl 5):

my $compress = do {
    my $previous;
    sub ($x) {
        $x ne $previous ?? $previous = $x !! return;
    };
}

That works just fine, but it might give someone pause :) Of course, I wouldn't write it like that for production.
