-- CHECK THAT LENGTHS MUST MATCH IN ARRAY AND SLICE ASSIGNMENTS.
-- MORE SPECIFICALLY, TEST THAT ARRAY ASSIGNMENTS WITH MATCHING
-- LENGTHS DO NOT CAUSE CONSTRAINT_ERROR TO BE RAISED AND

-- THIS IS A SPECIAL CASE IN

-- WHICH TREATS ARRAYS OF LENGTH GREATER THAN INTEGER'LAST .
-- AN ADDITIONAL OBJECTIVE OF THIS TEST IS TO CHECK WHETHER LENGTH
