Re: [boost] types_promotion_traits

Does what operator is being applied ever make a difference in the type
promotion? If this is the case then the traits would need a third
parameter, perhaps a tag for the operator. In the following example it
would be something like "add_tag".

types_promotion_traits<add_tag, T1, T2>::type
