ToLength have different behavior for negative values than ToUint32?
The wrap-around semantics of ToUint is completely crazy, and would be even
crazier when applied to random ranges like 0..2^53. Using -1 as a
(non-)limit
used to work more by accident than by design. But admittedly, the crop
semantics
of ToLength isn't great either. It would be best to throw, but that might
have
broken too much code. Just guessing, I'm afraid I don't know the exact
motivation.
