I know the original specification of C++ only allows class names as template parameters, but recent C++ developes allow a larger body of parameters to templates (see (first reasonable link I could find) here for example) -- this type of specification is commonly used to demonstrate how one can do fibonaci calculations all at compile time, rather than run time. Mind you, all these have to be specified at compile time, so that my method would not work with a board that could be dynamically allocated. But from a naming classification, you're talking about the slight difference between a Point-on-an-X-by-Y board, and a Point that knows it's on an X-by-Y board. Minor here, but could be significant in other cases.

It's not what you know, but knowing how to find it if you don't know that's important
