Even this doesn't work: import module namespace file = "http://expath.org/ns/file";; declare variable $file := "C:\data.txt"; let $data := file:read-text($file) return $data; file:delete($file);
I think that even if scoping worked it wouldn't be sufficient. A user should be able to read data into a global variable and delete a file, no? In this case the user wants materialization in memory not only on windows but also on any other OS, right? This example throws an error even on linux: import module namespace file = "http://expath.org/ns/file";; declare variable $file := "/home/dknochen/test.txt"; declare variable $data := (); $data := file:read-text($file); file:delete($file); $data As the streaming part is hidden from the user, the materialization part could be hidden as well, don't you think? For this we need to identify the operations that force materialization. Would that make sense?

If you execute the attached example on a windows machine you will get: user-defined error [file:FOFL9999]: An unknown error occured: "C:\data.txt": I/O error: 32 failed (error The process cannot access the file because it is being used by another process): Can not delete file: C:\data.txt; raised at zorba\modules\org\expath\ns\file.xq.src\file_function.cpp:82 The problem is that the file cannot be deleted as long as the file stream is open. This example query works on linux. This makes the 2 tests test/rbkt/zorba/file/copy_* fail on windows. Any idea how to solve this?
