BaseX identifies test.xq as updating expression, while test1.xq, test2.xq are not considered updating expressions. This makes invoke.xq fail with "[BBXQ0001] No updating expression allowed." on https://github.com/BaseXdb/basex/commit/e6f2ef714e1bd53bcca54f502a5fd2739a07026c Expected result would be: 4 4 4 Issue at https://github.com/BaseXdb/base…

invoke.xq

xquery version "3.0";

xquery:invoke( file:dir-name(static-base-uri()) || "test1.xq" ),
xquery:invoke( file:dir-name(static-base-uri()) || "test2.xq" ),
xquery:invoke( file:dir-name(static-base-uri()) || "test.xq"  )

test.xq

xquery version "3.0";

declare function local:bar() as xs:integer {
  xquery:eval(local:fun()())
};

declare function local:fun() as function(*) {
  function() { "4" }
};

local:bar()

test1.xq

xquery version "3.0";

declare function local:bar() as xs:integer {
  xquery:eval(function() { "4" }())
};

local:bar()

test2.xq

xquery version "3.0";

declare function local:fun() as function(*) {
  function() { "4" }
};

xquery:eval(local:fun()())

@LeoWoerteler: any idea?
