One of the reasons we don't allow atomic values on the LHS of "/" is that
people felt it was not acceptable that let $x := 10 return $x/2 should be legal
and return 2. Though you get the same problem with @price/2 which is legal
today and returns 2...

The other problem with overloading "/" is that there's also a need for simple
mapping (without deduplication and sorting) with nodes on the RHS, for example
//@href/doc(.)
