Safe variadic functions with parameter count checking. For example consider a constructor of the N dimensional vector of T takes only N farameters that are convertable to T and fails othervise: Are you sure this is right? It seems that the N parameters are dimensions and should be convertable to an integer like size_t. T is the value_type and could be anything?
Sorry, i guess i want. clear enough. vector template is defined like this: template <class T, size_t N> class vector; Where T is arbitrary type (supposedly arithmetic, or it woult be meaningless otherwise) and N is an amount of components in a vector (aka vector dimension or size) and not an amount of dimensions in an array (vector is a one dimensional array of elements). So vector is statically sized, and parameters passed to constructor are values to be stored in it and not sizes of corresponding array dimensions.
