Generally, I don't like these trailing commas, but indeed there is some
value for lists that often have to be split across multiple lines. As
such, my threshold is whether splitting certain lists across multiple
lines is sensible. In my opinion, the following lists should usually be
one-liners (because having too many items in the list would be a general
design issue):
* function/method *parameters*
* interface implementations on a class
* trait implementations on a class
* class member list (I prefer a distinct statement for each member)
* inheriting variables from the parent scope in anonymous functions
An improvement might be allowing trailing commas in grouped namespaces,
but I haven't enough experience with these to form an opinion.
The only other case where allowing trailing commas would make sense, in
my opinion, are function/methods *arguments* – there is, unfortunately
for me, no explicit voting option.
