// Nothing like a little CPP abuse to brighten everyone's day. Would
// have been nice to do this with template functions but as of 2.5.x,
// g++ seems to fail in various ways, either not resolving general
// template functions, or not instatiating non-member template
// functions.
//
// When templates work more reliably in g++, this will be replaced by
// the MArray class.
