I've sometimes experimented with the coding style:

declare function f($x as element()) {
    ... body of the function goes here ...


but I don't really find it very comfortable. Sticking the $x in at the start
of every path expression gets tedious, but it's more familiar to readers.


let . := expr 
return expr


for . in expr return expr

would be nicer. But I'm not sure. The fact that some expressions in XQuery
change the focus and other similar expressions don't is confusing, but most
attempts to fix it are only likely to add to the confusion.
