It looks like all you need is a way to toggle attributes with a 
flag, like pure(isPure) or something.  IIRC, last time that came 
up, it turned into a bikeshedding fest about the syntax.  (I 
don't think parentheses works with UDAs.)  Anyway, yeah, we need 
the functionality.

However, this DIP is *way* more complicated.  I stand by what I 
said before:
