GLU embedded in C++: a marriage between multidimensional and object-oriented programming

The embedding of a small but expressive language of multidimensional functional programming in a well known and widely used language of object-oriented programming leads to the combination of two radically different programming models. In this paper, we formally define the syntax and semantics of GLU , which can be thought of as the multidimensional core of Lucid and GLU, and we describe its implementation as a language embedded in C++. With the aid of a few examples, we argue that the marriage of the two programming models is not only compatible and natural, but also that it produces a new and interesting hybrid language.
