Ayaz Hafiz	759127660d	Spread list tests can never touch exact-sized bounds tests ... When compiling a pattern match like ``` [] -> .. [_] -> .. [_, ..] -> .. ``` to a decision tree, we must make sure that the last test (len >= 1) does not touch the branch reached by the second test (len == 1). It is enough to ban (len >=) tests from ever touching exact-sized list patterns, because a spread test (len >=) can never reach an exact-sized test. On the other hand, an exact-sized test can reach a spread pattern, because in ``` [_, _] -> .. [..] -> .. ``` the last branch generates tests for patterns `[]` and `[_]`, and we would like those patterns to be covered by the spread test (len >= 0)! Closes #4685	2022-12-05 13:45:35 -06:00
