> Allowing trailing commas in structured literals (array, set, map) as a convenient syntactic leniency. :)
> {code:java}
> let m = { "foo": 1, "bar": 2, };
> let a = [ 1, 2, ];
> let s = (1, 2, );{code}
> Using a trailing ellipsis (...) to alter the concrete class materialized as a convenient semantic shortcut.
> {code:java}
> let m = { "foo": 1, "bar": 2, ... }; // LinkedHashMap
> let a = [ 1, 2, ...]; // ArrayList
> let s = (1, 2, ...); // LinkedHashSet{code}
