I guess not needing to name the container type will happen only for 
C++0x. But lot of time 'till then ;)

But I'm quite happy with the crange<container> compromise so far, since 
you do know the container type, once you use it (it's its type, that is :D)

of course ;) the element type is deduced from the container type.
For instance, if you want a constant range, just do:
crange<const container> r(cont);
//... etc
