It's sensible. OTOH, it's limited for one type, which is simpler.

As I've said previously, your solution appears simple enough to me, so I've no 
problem with that kind of flexibily. The only issues are
1. How to specify formatting style for all vectors, or for all sets, etc.
2. How to handle nested containers.

I'll get to this in another email.
