Subject: Re: [PHP-DEV][RFC][DISCUSSION] Deprecate the backtick operator

I totally agree to deprecate and remove it in 8.0.

Some reasons:

It usage is very rare (actually, I don't remeber the last time that I see
that in use). Even in old codes.

It too could causes confusion with single-quote in some fonts, sizes and
styles.

Is more easy to identify shell_exec() than backtick usage, anyway.

It have exactly the same behaviour than shell_exec(). Do not need adapt
usage beyond of the replacement itself.

Some keyboard layouts (like mine, ABNT2) requires to press shift+backtick
key then space to print a single backtick. Other option is I print two
backticks at sametime (is what I do when I work with Markdown).

Backtick inside backtick requires a most rare slash backtick to escape it:
`\`` (actually, I even know if it works haha)

Bonus/curiosity: is hard to find the definition of backtick if you don't
know the name of this symbol in english. In portuguese it is called "acento
grave" (something like "grave accent").

The remotion of this "feature" will allow use the backtick character to
another thing futurely (which could be decided carefully). Or even unused
forever.
