Would isset($suffix) not suffice here? There are several things I've
thought of that would be other alternatives to changing this language
construct, but as I don't have my laptop with me, some of the testing to
confirm behavior will have to wait.

Other concerns fall around list() already being a difficult thing for
people to understand, let alone use properly. Making it look even more like
a function definition would likely exacerbate this.

Agreed. This comes up for me every time I want to parse a text file
(including about 30 minutes ago, as it happens).
