[Message part 1 (text/plain, inline)]

Hi, everyone,

I have just noticed that `grep -P '[\d]' <<< 'asdf 1234 asdf'` does not work, while `grep -P '[0-9]' <<< 'asdf 1234 asdf'` works as expected. When `\d` is used outside of square brackets, it works as expected.
I have no idea why `[\d]` does not work, but after I open this SO question, it seems to be a problem at least in `grep <at> 3.10` or `3.7+` (excluding `3.7`).
Note that I use Arch Linux and I have installed `grep` from the official repositories.
`grep` version I currently use:

How this helps someone to find the bug in the code. :)
