While the idea to delay the construction of the QVLAs until we know we need them is elegant, we're doing a lot of checks twice or thrice this way, so merely re-set the a, b pointers and otherwise continue executing. This requires us to default-construct the QVLAs before potentially assign()ing to them, but that ought to be cheap, given the compiler can see everything that's going on in QVLA.
