I'll try to pose it differently.

How would you implement the following using your library?

    Magic<8,32> m;
    m.put(0xAA);
    m.put(0xBB);
    m.put(0xCC);
    m.put(0xDD);
    assert(m.get() == 0xAABBCCDD);

What about supporting this slightly more complicated case?

    Magic<16,32> m;
    m.put(0xAAAA);
    m.put(0xBBBB);
    assert(m.get() == 0xAAAABBBB);

And how about this far more challenging one?

    Magic<4, 16> m;
    m.put(0xA);
    m.put(0xB);
    m.put(0xC);
    m.put(0xD);
    assert(m.get() == 0xABCD);

I think I see how I'd do the first, and probably the second, but the
third may require a very different approach.
