ruby-core #85786
Issue #14500 has been updated by Sundeep (Sundeep Agarwal).
oh, I didn't check with `$10`. I'd tried with backreference. Any idea how to use `\10`?
```
$ echo 'abcdefghij' | ruby -pe 'sub(/(.)(.)(.)(.)(.)(.)(.)(.)(.)(.)/, ":\\9:")'
:i:
$ echo 'abcdefghij' | ruby -pe 'sub(/(.)(.)(.)(.)(.)(.)(.)(.)(.)(.)/, ":\\10:")'
:a0:
$ echo 'abcdefghij' | ruby -pe 'sub(/(.)(.)(.)(.)(.)(.)(.)(.)(.)(.)/){":#{$10}:"}'
:j:
```

* formatting issue: `n<sup>th</sup>`
* suggestion to add a note on `\0` similar to the note mentioned in **Special global variables** (https://ruby-doc.org/core-2.5.0/Regexp.html#class-Regexp-label-Special+global+variables) section about `$&`

* suggestion to add documentation on `\K`
* need clarification if the below behavior seen is expected and mention it while adding documentation
```
$ echo 'aaa' | ruby -pe 'gsub(/a\K/, ":")'
a:aa:
$ # what I expected
$ echo 'aaa' | ruby -pe 'gsub(/(a)/, "\\1:")'
