As mentioned before I’m really looking forward to Typed Properties that will land in PHP 7.4 (now in alpha!). Brent has done a full writeup on ‘m:
In this post we’ll look at the feature in-depth, but first let’s start by summarising the most important points:

And no, the variadic function syntax is not a closing solution workaround for this.
