It's utf8ical, actually.

Yes, they're equivalent. But don't do that.

It's strictly utf8ical. Use $^02 if you're really insane enough to
have 10 curried parameters. Or got to hex $^2 .. $^a.
: What's happened with C<{ $^_ - $^_ }>? Are those two the same
: parameter now? Or two different 'anonymous' parameters?
$^_ would sort between the lower case letters and the uppercase.
$_ is preferred if there is only one parameter. It's special-cased
to alias the first parameter in any bare closure.
