Should I also read this as strings *will* respond to "+"?

Assuming that's a yes and that you go with the current syntax proposal
for collections, I think it should be a long term goal to replace
String+ with String|. To that end, I think String+ should be marked as
deprecated right out of the gate. String+ should also be implemented
as expanding to String|.
