Data.PrimitiveArray.Dense

Dense primitive arrays where the lower index is zero (or the equivalent of zero for newtypes and enumerations).

Actual writes to data structures use a more safe write instead of the unsafe unsafeWrite. Writes also tend to occur much less in DP algorithms (say, N^2 writes for an N^3 time algorithm -- mostly reads are being executed).

TODO consider if we want to force the lower index to be zero, or allow non-zero lower indices. Will have to be considered together with the Index.Class module!

TODO while Unboxed is, in princile, Hashable, we'd need the corresponding VU.Vector instances ...

TODO rename to Dense.Vector, since there are other possibilities to store, without basing on vector.
