-- A storable array is an IO-mutable array which stores its
-- contents in a contiguous memory block living in the C
-- heap. Elements are stored according to the class 'Storable'.
-- You can obtain the pointer to the array contents to manipulate
-- elements from languages like C.
--
-- It is similar to 'Data.Array.IO.IOUArray' but slower.
-- Its advantage is that it's compatible with C.
--
-- Safe API only of "Data.Array.Storable".
