[Haskell-cafe] representation on persistent store question

The second data structure is an array of structure .. the third set of
structure are a series of "bit" lists ... Each array element  has an offset
for its  corresponding "bit list":

[{........, offset: Int64}] [[bit]]

when I marshall up all this "offset" should be the serialized/"marshalled"
offset of its correponding [bit]!!

Regards, Vasili
