Trivia alert -- in XPath 2.0 there are a number of ways to do this:

$x/.
$x|$x
$x|()
$x intersect $x
$x except ()

basically anything that involves any of the set operators but doesn't otherwise modify the sequence.

I agree that $x/. is hard to beat, especially for those with limited keyboard skills. (Plus, the way it works is really obscure, which in some quarters will mean artful.)

Cheers,
Wendell

That is a great tip....

the best thing about it, on a UK keyboard at least, is that it only requires typing two characters, on adjacent keys, with the right hand. So there's a greater than 50% chance of typing it without introducing a typing error, which can't be said of every xpath (or English) construct.
