That doesn't actually say your example should work. It mentions:

    $locator = { .<here> }
    $obj.$locator            # $obj<here>

Which is a closure, not an anonymous method, and when it does mention
the anonymous method syntax, it uses self. Plus I don't see anywhere
else in S12 that it states that the invocant is in $_ by default for a
method. Asked TimToady to confirm either way, then will either implement
that if it's meant to be implemented, or reject the ticket (and remove
the incorrect test) otherwise.

Thanks,
