> [~davies]'s suggestion on how to rewrite it to be more clear:
> {code}
> Seq.tabulate(outputBitsetWords) { i =>
> val bitset = if (i< bitset1Words) {
> getLong(obj1, i * 8)
> } else if (i == bitset1Words && bitset1Remainder > 0) {
> getLong(obj1, i* 8) | getLong(obj2, 0) >>> bitset1Remainder
> } else {
> getLong(obj2, i - bitset1Words) <<< bitset1Remainder | getLong(obj2 i -
> bitset1Words + 1) >>> bitset1Remainder
> }
> putLong(buf, i * 8, bitset)
> }
> {code}
