"Hamlet"
I'm (desperately) looking for a serious comparative review of Loki vs. Boost libraries. Although the differences are quite clear, still it would be nice to see a serious comparison, especially in the features that exists in both places, i.e. smart pointers,
Highly controversial. You might see some new developments in the coming weeks. Stay tuned.
small obj. allocator,
Not 100% sure how it compares or relates to boost::pool, but my general impression is that there is overlap, but around the 30-50% level. That is, they actually don't have the same goals and behaviour.
type traits
I believe Andrei himself has said that the boost::type_traits are more complete. I think taking a look will pretty much confirm that.
and template meta-programming.
Again, highly controversial. Technically, you can do things "the Loki way" in MPL, but I don't know enough about either to illustrate. To that extent, I believe that MPL is more or less a proper superset of Loki::TypeList.
Does anybody knows if there exists such a paper somewhere, or alternatively have his own insights about the libraries?
Not sure about such a paper, but take my opinions expressed here with a grain of salt. ;) Dave
