  40  * Brendan: "need to test cases Math.pow(2,32) and greater to see
  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.
