In this case (if this is a such good feature) IMO we should think about
making the trailing commas *required*. In this way we will be consistent in
either do we have trailing commas in Swift or don't. Otherwise we'll have a
zoo in our sources/projects.
I don't think we need to have the same rules for commas "everywhere we have
comma-delimited syntax".

+1 from me. We should be consistent in either accepting or rejecting
trailing commas everywhere we have comma-delimited syntax. I'm in favor of
accepting it, since it's popular in languages where it's supported to
enable a minimal-diff style, so that changes to code don't impact
neighboring lines for purely syntactic reasons. If you add an argument to a
function, without trailing comma support, a comma has to be added to dirty
the previous line:
