Just in case any one is curious, a euclidean vector is represented by its Cartesian coordinates: (*p*0, *p*1,..., *p*d - 1) (in a d-dimensional vectorial space). It can be defined by the difference between two points (Locations), A and B: if A has coordinates (*a*0, *a*1,..., *a*d - 1) and B (*b*0, *b*1,..., *b*d - 1), then vector [image: $ \bf AB$] = *B* - *A* has coordinates (*b*0 - *a*0, *b*1 - *a*1,..., *b*d - 1 - *a*d - 1). The requirements of Euclidean Vector are very similar to those of Location, and could actually have been represented by a Location. However, an euclidean vector is very different from a point, or location, (from a mathematical point of view) and it would have been confusing to represent these two entities by the same *concept*. Yes, I'd be interested. Looking forward to reviewing your library. I'm not shur that I have any comments right now other than to say that it would be a great addition.
