I guess some of my confusion comes from reading

some time ago. I think this article is why I thought they were a bonus for compilation time.
In particular, page 33, in the last sentence before section 3, says:
Section 4 demonstrates how variadic templates drastically reduce compilation times
I believe that they do/can. However, getting the most performance out of variadic templates involves avoiding O(N) recursive template instantiations, which can be maddeningly difficult to achieve for some problems. -- Dave Abrahams BoostPro Computing Software Development Training http://www.boostpro.com Clang/LLVM/EDG Compilers C++ Boost
