[boost] [mpl, fusion] minimal conforming sequence

Hi,

Assume that I have a custom type sequence S that has two operations, 
size<S>::value and element<S,I>::type (with whatever spelling).

What needs to be done to adapt S into a conforming MPL or Fusion sequence?

In a perfect world, the answer would not require the inclusion any MPL or 
Fusion headers and would consist of three specializations. ;-)
