Oh, and under the S02 rules above (the index expression inherits
outer context on RHS), Pugs currently does this:

    $_ = %x{ 1, 2 }   
        --- reduces to ---
        $_ = %x{ [1, 2] }
            --- reduces to ---
            $_ = %x{ "1 2" }

Which is, well, very surprising.  Where did I get wrong?
