Can you get it to use arbitrary precision integers on overflow?
Maybe, if someone implemented a crate for that already. Right now I was just using the latest primitives available.
There are some bignum crates, but nothing transparent. Most don't expect + on a number to allocate
wasn't this the stated reasoning for stabilizing the ops traits to take ownership of their arguments?
Some Add impls do allocate; of course, but on types that already do, like String. Not &str.
So by the same token, Add for a BigInt makes sense, but u128 + u128 = BigInt may be surprising.
