Damian Conway,
the original author of the code in question, says:
That's so baroque, I'm sure it must originally have been intentional,
though it's now clearly vestigial.
An earlier version probably did something like:
foreach (@{[@{$_[0]}]}) {...}
where the inline copy was essential, presumably to prevent
$_ iterating
the original arguments. And then I simply forgot to correct it when I
changed the structure.
I've changed it now. Thanks.
