Not well-specified (does order matter? how about repeated values? is
(a;b;c) an object? it sure looks like one, and if so, object in L
already has a meaning).  But for one obvious interpretation:

    {a, b, c} <= set(L)

and in this interpretation you should probably optimize to

    {a, b, c} <= L

by constructing L as a set in the first place.  Really this thread
probably belongs on python-list anyway.
