Review Comment:
was the pattern in the previous comment example insufficient? I think the
current approach to optionally multiply by negative makes things slightly
longer to follow what the code is trying to achieve.
fyi note ideally we use `next_token_ref` since that avoid cloning,
especially given that `parse::<i64>` does not require an owned value
