that's a very good idea. But I would wrap them in some kind of GiNaC 
class then like lst does with STL::list.

But from your example (using exvector and the boost lib) I get the 
impression you don't like that kind of wrapping ... ?
Anyway, it looks like a good improvement, at least as long as we don't 
care about inequalities ;-).
