Hmm, sounds somewhat better. Well, the implementor can define the 
parameters last if he wants to be free to reorder afterwards.

They do not have to be mangled, but the implementor might want to 
generate a hash from named parameters to the mangling, to avoid 
linking to a function that has different named parameters.

My symphaties. Ask Mike to mark the DIP postponed? Walter's DIP 
has not yet passed the reviews, so there's always the possibility 
that someone uncovers a major flaw. In that case, it's good to 
have a backup DIP.
