This is strange, I've never encountered it before...maybe it is just a
result of the layered texture definition being in a macro, so the parser
doesn't expect that construction.

It might work if you declared the layered texture as a local variable:

#macro()
    #local localTex =
    texture {}
    texture {}

But I don't know how you would return the texture..."texture {localTex}"
would get picked up as a third layer, I think you would have to return
"localTex" and wrap the macro call in a texture {} block. Assuming this
trick actually helps...

Hopefully, a future version of POV-Ray will have an improved syntax for
defining layered textures...
