For this, it would be nice to have a start parameter for enumerate().
Why would it be nice? What would you use it for?
The only thing I can think of is printing lines with line numbers, and
starting those line numbers at one instead of zero. If that's the only
use-case, should it require built-in support?
It's fairly common in financial applications to number checks in
batches, from a starting point that depends on the number of checks
issued in previous runs. Having a start point would allow this to be
done more simply, though it's not anyway what I would call an onerous task.
