Description:
------------
I find it hard to find reference documentation on argument unpacking, aka the spread operator, aka the splat operator, aka the ... operator, aka the ... token.

It's mentioned as new feature on several places: 

https://www.php.net/manual/en/migration56.new-features.php
https://www.php.net/manual/en/migration74.new-features.php
https://www.php.net/manual/en/functions.arguments.php#functions.variable-arg-list.new

I would appreciate a complete reference page on argument unpacking, with examples and version info (comparable to https://www.php.net/manual/en/language.operators.errorcontrol.php).

This feature is particularly useful when you have a list of arguments in an array and you want to pass them to a function without manually indexing each element.(https://github.com)(https://www-lhiproviderportal.com)

@Vrana: the url you post is one of the places where the ... token is mentioned, as I wrote in the initial description. 
But using the ... token for a variable-length function argument is just one use case. 
Other uses of the ... token are not documented, unlike most other operators
(https://www.php.net/manual/en/language.operators.php).
