How about a helper traits class?
template <typename T, int Rank> struct SliceType { typedef typename MyArray<T, Rank-1> type; };
template <typename T> struct SliceType<T,1> { typedef T type; };
template <typename T, int Rank> typename SliceType<T,Rank>::type MyArray<T,Rank> :: operator[] (const int& index) throw();
With a great deal of thanks to Martin, and a few hours sleep, I've got the thing working. ... Sorry for the noise everyone, and in future I'll try not to post anything unless I've been otherwise well rested. Cheers, -- Manfred Doudar MetOcean Engineers www.metoceanengineers.com
