Re: [Boost-users] question: boost::array does not have compile time checked access

Fwiw, the tuple interface has been added to std::tr1::array:

Section 6.2.2.5.

FWIW, that's ultimately the wrong generic interface for access to fixed-length structures. It's okay for array, but for most tuple implementations it generates O(N^2) template instantiations for a traversal of N elements. I hope the Boost Fusion library and related work will give us something better to propose soon. -- Dave Abrahams Boost Consulting www.boost-consulting.com
