This syntax is an archaism that POV-Ray inherited from DKBTrace. I guess it's a
bit unsettling at first, but I don't see any major reason to change it, and even
if new syntax were added to wrap layered textures into a single unit, we'd want
the old syntax to be retained for a while, for use in existing scene files &
macros. And because layered textures don't have any form of wrapping, I suspect
that it would be a bit tricky to write a script to convert the current syntax
automatically without the script being generally aware of POV SDL syntax.
