Replying to myself: It just occurred to me that array destructuring
already allows omitting values:
[, , $username] = getUserData();
I still do find using void here more clear though, more intentional.

Given the array destructuring syntax, an alternative syntax might be:
function foo($arg,)
Again, I would prefer to see void here in stead of a trailing comma. In
function calls a trailing comma is already allowed and it has a
completely different meaning, which can be confusing.
