Public bug reported:

In XQuery 3.0, it is possible to make forward references to global
variables, like in:

declare variable $x := 3 + $b;
declare variable $b := 4;
$x

Such forward references can cause circular dependencies like in:

declare variable $x := 3 + $b;
declare variable $b := $x;
$x

This needs to be detected and the error XQST0054 thrown. Currently,
Zorba throws XPST0008
