Data.Array.Parallel.Unlifted.ArrayArray
Description
Irregular 2D unboxed arrays.
The difference between this type and something like
Data.Vector (Data.Vector.Unboxed a) is that the inner arrays have kind
# and cannot be bottom. This ensures that we can always lookup an element
from an ArrayArray# without performing unboxings or checking for thunks.
