     41  * whether they round-trip." Reason: thanks to the work done in
     42  * http://bugzilla.mozilla.org/show_bug.cgi?id=124339, lastIndex
     43  * is now stored as a double instead of a uint32 (unsigned integer).
     44  *
     45  * Note 2^32 -1 is the upper bound for uint32's, but doubles can go
     46  * all the way up to Number.MAX_VALUE. So that's why we need cases
     47  * between those two numbers.
