Two class templates, one using variadic parameters to model a multidimensional array, the other a multidimensional array adaptor on top of a container class
Besides the aforementioned container (array_md) and adaptor (multiarray) class templates, there are two helper sub-libraries. The indexing_result and indexing_noexcept type-traits class templates calculate the result type and exception status of a chain of operator [] calls. The slice function templates carry out a chain of operator [] calls with the base and index objects/values given as variadic function arguments; they have bounds-checking counterparts called checked_slice.
The four sub-libraries require C++2011 features, so your compiler and standard library has to support being run in C++11 mode.
The format of the library is like a prototype Boost library submission. As such, the code is under the Boost Software License.
