----------------------+-----------------------------------------------------
 Inside an import library, code like

   (eval '(import scheme chicken numbers))

 will generate warnings about re-imports (in this example for numerical
 standard procedures). This should be disabled in (`##sys#expand-import`)
 during the executing of the import form in the import library.
