Test suite test for element types other than Char, because there can be bugs with respect to pointer arithmetic (actually there was one in reverse) tests for StorableVector.Lazy tests for StorableVector.ST StorableVector.Cursor An unboxed mutable array with a cursor for the next element to be evaluated, where new elements are generated and the cursor is advanced in a lazy manner. This way we can simulate a lazy list with strict elements in a memory and time efficient way.
