Valid, yes... but collapsible code blocks might actually encourage better coding
behavior.  In your example, the preferred alternative is obvious:

pigment
{
  #if (true)
    color rgb x
  #else
    color rgb y
  #end
}

I can't really think of a valid circumstance where the 'looser' form is
necessary (or advantageous)...
