I didn't invoke your macro first time - just added it to a test file.
_Using_ it now gives me an error but I can't see anything wrong in the
script ( that pigment{ Green } in my post shouldn't be there).

OK - there's an extra brace above. Sorry. No problems when corrected.

The current form for layered textures is not very good, after all. It causes
too many ambiguities to both the parser and the user. IMHO it should be
redesigned for pov4.
  For example something like:

texture
{ layered texture_map
  { [1 texture1]
    [1 texture2]
  }
}

  'layered' could work like 'average', but layering the textures instead
of averaging them. The values could be used for some extra effect (don't
know if there's any useful thing, though).

This does not look like a POV-Ray 3.5 specific problem to me.  If it is,
please post a correct bug report with a sample scene showing the problem. 
It it is just a problem about POV-Ray in general that occured to you while
working you should post it in a different newsgroup.
