Hi Ion,

Sometimes I need to go through all elements in such a container. 
However, it is know that the number of elements is low, so I unroll the 
loop manually. In that case I would like to be able to do the following:

const T& t1 = flat_set[0u];
const T& t2 = flat_set[1u];

Alternatively, provide a base() function that directly give read access 
to the underlying container:

const T& t1 = flat_set.base()[0u];

Comments?
