You should know that 10 years ago people didn't even imagine the kind of
template usages that you are assuming as obvious. Indeed, everyone wants
to tell unions from classes now and you bet, it will be possible sometime
in the future, likely not using SFINAE at all. Before posting other
messages with this attitude, please, please have a look to the papers
available from the ISO Web site:

Thanks.
