Subject: Adding new closing tag =?> for keeping trailing newline
From: sji@sj-i.dev (shinji igarashi)

Hello everyone,

I'd like to propose adding a new closing tag `=?>` to the language.

PHP currently removes the newline character immediately following
the closing tag `?>`.

With the new closing tag `=?>`,  the code should look like this:

```
- <?= 1 =?>
- <?= 2 =?>
- <?= 3 =?>
```

and the results it produces would be:

```
- 1
- 2
- 3
```

instead of the following:

```
- 1- 2- 3
```

This addition requires only a one-line modification to the lexer and
doesn't break BC. The proposed patch is here.
https://github.com/php/php-src/pull/8708

Before writing an RFC, I would like to hear your input on whether
it's worth tackling.

Thanks!
