Hi Paulo,

Odd.  I don't understand the documentation too, then --- I would have 
expected use-mapping? to let us get the imported module variable.

Here's an example that appears to get at *ht-append*:

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
(module test mzscheme
   (require (lib "texpict.ss" "texpict"))
   (define my-ht-append
     (namespace-variable-value
      'ht-append
      #t
      (lambda () #f)
      (module->namespace '(lib "texpict.ss" "texpict")))))
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

but I don't yet understand why your example doesn't work yet.

Best of wishes!
