Hi internals!

This RFC proposes to add a syntax for argument unpacking:


     https://wiki.php.net/rfc/argument_unpacking


Basically, this is the "complement" of the variadics RFC: It is not about
declaring variadic functions, but about calling them.

The syntax it introduces looks as follows:


     $db->query($query, ...$params);
seems so weird and ugly.. -1 I totally agree.. the syntax design doesn't look quiet right. it isn't readable and ugly. Since it's unpacking the arguments from the caller, the "..." should be put after the $params. e.g. 
     $db->query($query, $params...);
the above approach is also used in Go. Not sure why you've picked this up now, but the mail you're replying to is from nearly two years ago, and the syntax in question was accepted, and released as part of PHP 5.6.0 in August 2014. The documentation can be found here: http://php.net/functions.arguments#functions.variable-arg-list So it's far too late to change the syntax, even if we had a better reason than "it looks nicer to me with the ... the other side of the name".
