I don't want to encourage "if it compiles, ship it!" I've strongly disagreed 
with the C++ concepts folks on that issue, and they've downvoted me to hell on 
it, too :-)

I get the impression that I'm the only one who thinks exclusive traits is more 
of a problem than a solution. It's deja vu all over again with Exception 
Specifications. So, one of:

1. I'm dead wrong.
2. I fail to explain my argument properly (not the first time that's happened, 
fer sure).
3. People strongly want to believe in traits.
4. Smart people say it tastes great and is less filling, so there's a bandwagon 
effect.
5. The concepts/traits people have done a fantastic job convincing people that 
the emperor is wearing the latest fashion :-)

It's also clear that traits work very well "in the small", i.e. in 
specifications of the feature, presentation slide decks, tutorials, etc. Just 
like Exception Specifications did. It's the complex hierarchies where it fell apart.
