As I said in my reply to Nick, this proposal makes no distinction 
between conversions done in the context of a comparison and 
conversions done in any other context.

I would rather not introduce a special case for comparisons, 
since special cases generally make the language more complex and 
harder to use. However, if you think this is a good idea, I 
encourage you to submit it as a separate proposal.
