[ruby-core:121727] [Ruby Feature#21284] Request: add `Array#pad` method

[MatzFan (Brian Cohen) via ruby-core]

Issue #21284 has been reported by MatzFan (Brian Cohen).

----------------------------------------
Feature #21284: Request: add `Array#pad` method
https://bugs.ruby-lang.org/issues/21284

* Author: MatzFan (Brian Cohen)
* Status: Open
----------------------------------------
A method to pad an array of arbitrary length with objects up to a specified array size does not currently exist.

`Array#fill` does not do this and I therefore propose the following method:

``` ruby
class Array
  def pad(pad_to_length, object = nil)
    fill(object, size, pad_to_length - size)
  end
end
```

I have provided an [answer](https://stackoverflow.com/a/79591610/4114896) to a Stack Overflow question asking how this can be done in Ruby. I've also explained in a comment on the answer which suggests using `Array#fill` why this does not meet the exact need.

It may be possible with `Array#fill` and start-exclusive range?

```ruby
ary.fill(object, -1^..padding_length)
```

When I try and run that code, e.g.
``` ruby
[1, 2, 3].fill(nil, -1^..10)
```


``` shell
'Integer#^': Range can't be coerced into Integer (TypeError)
```
In any case `pad(10)` is much prettier IMHO.

Current Ruby doesn't have start-exclusive range.
`^..` is so-called neko-operator in Perl 6, and just this request reminded me of it, sorry.

No worries, I thought it was some new syntax I was not aware of!

What should happen if the size is smaller than what currently set?

> What should happen if the size is smaller than what currently set?

If the `pad_to_length` argument is less than or equal to the array's current size the array is returned unchanged. If it is larger, elements of the specified kind are pushed to the array until it reaches `pad_to_length` size and the modified array returned.
