[basex-talk] Unpredictable function return types seems to default to item()? instead of item()*. Applies to 9.4.2

Hi,

Thank you Christian for the new 9.4.2. release!

The function "f()" below will yield to the error: "Cannot promote item()? to xs:integer?: $result_4" This works in BaseX 9.1

------

declare function local:f() as xs:integer()*{ let $id := client:connect("localhost", 1984, "admin", "admin") let $result := client:query($id, "1,2") let $close := client:close($id) return $result };

local:f()

-----

I guess, that unpredictable return types at compile time default to item()? instead of item()* and thus cannot be used in a function returning anything else but item()?

Has someone an idea for a solution/workaround for this?

Best regards, Sebastian
