      If the module or package is accessible via the normal import
      mechanism, a wrapper around the relevant part of that machinery
      is returned.  Returns None if the module cannot be found or imported.
      If the named module is not already imported, its containing package
      (if any) is imported, in order to establish the package __path__.
  
      This function uses iter_importers(), and is thus subject to the same
      limitations regarding platform-specific special import locations such
      as the Windows registry.
