Ah, thanks for that.

In many cases "for" expressions can now be written with the "!" operator, and
in this case you can use position().
For example
for $i in 1 to count($seq)) return $i * seq[$i]
can now be written as
$seq ! (. * position())

In Xpath2, there was no super-concise method of extracting the
position of a ranging variable in a for expression.
For example, in the expression "for $i in $seq return [expression]",
you could not use $i/position() to give you the position of $i.
Instead you had to rewrite as "for $n in 1 to count($seq)"... and then
use $n or $seq[$n] as needed.
I'm writing to ask whether there is any new method in Xpath3 that
provides a more concise method of referencing the position of a bound
range variable.
