Here is another example:
(for $x in 1 to f() return g($x)) = (for $x in 1 to f() return h($x))
Imagine that f() is a non-deterministic function that returns 1 the first time
it is called and 2 the second time it is called. This is a perfectly
acceptable non-deterministic function.
However, the number of calls to g and h are determined by the result returned
from f(). That means that the two calls to f() cannot be reordered, and so the
arguments to the = operator cannot be reordered.
