i really would not do that. you cant see the concrete meaning of 
vector1.cross(vector2). you cant tell if it just returns the cross 
product or if it stores the cross product in vector1.

so just stay clean and do the global v3 = cross(v1,v2). you see this 
formula, you understand it. and it is referentially transparent (i.e. no 
arguments get modified, 
http://en.wikipedia.org/wiki/Referential_transparency ).
just my opinion. and global namespace pollution? cant see it. cross is 
crossproduct same with dot. i cant see any other meaning. and if it is 
really something different, function overloading should resolve it.
