So, uhm, what *does* happen if I do
$hash{$pair} = "foo";
Runtime error? And what if I do this:
my %hash is keyed(REF);
$hash{bless $pair, "NotAPairReally"} = "foo";
...
for %hash.kv -> ($k, $v) {
bless $k, "PAIR";
}
Storing pairs as hash keys could lead to interestingly funky data
structures. I'm sad that this is being ruled out.
