Right, "callers Just Work" is carrying a lot of water here.  I want to know specifically how people think it should behave.  For example: What should happen in the case of a semantic conflict that can't be resolved during conversion?

(If you can't tell, I'm a bit annoyed about folks having plenty of energy to express their distaste with one solution, only to float a hand-wavy alternative lacking specifics that also has flaws; sorry, abs@, I'm not trying to pick on you here...).
