The current implementation doesn't support re-ordering anything.
This feature has come up a few times. Personally, I don't think
partials need to support this and every other potential feature; at
some point a regular or short closure should be used.
As a reminder, a `?` does not create a single argument in the
closure's signature. All these `$partial`s are the same, and here I do
not mean equivalent but literally the same:
function f($x, $y) {}
$partial = f(?);
$partial = f(?, ?);
$partial = f(?, ?, ?);
$partial = f(?, ?, ?, ?);
$partial = f(?, ?, ?, ?, ?);
