I'm willing to consider starting with A, though I think we should admit 
that the most likely reaction if we do that is "you idiots got it wrong 
again, we waited 25 years for underscore, and you don't even let us do 
it in the most obvious places."  So I don't think "do A and never do 
anything about method parameters" is going to fly, though it is 
potentially a reasonable incremental step on the way there to get people 
used to unnamed things.
