Issue #9587 has been updated by sawa (Tsuyoshi Sawada).
I now think that writing as below is good enough:
```ruby
6.times.with_index(1){|_, i| puts "Chapter#{i}"}
```
I withdraw this proposal. Please close it.

Feature #9587: Integer#times with optional starting value

----------------------------------------
Just like `Enumerator#with_index` takes an optional argument that specifies the initial value of the index, I would like to request that `Integer#times` take an optional argument that specifies the initial value. The usefulness of it is similar to that of `with_index` taking an argument. We sometimes want to repeat tasks a given number of times, and want to use an index not necessarily starting from `0`.
6.times(1){|i| puts "Chapter #{i}"}
should give
Chapter 1
Chapter 2
Chapter 3
Chapter 4
Chapter 5
Chapter 6
with the return value `6`. We can do it with `1.upto(6)`, or with `#{i + 1}` within the block, but giving the initial value to `times` is much easier.
