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. > Another case is the one where a function intentionally does not use one > of the arguments passed to it.

In function calls a trailing comma is already allowed and it has a completely different meaning, which can be confusing. Regards, Dik Takken
