I'd favor a different change: let final variables optionally

Afterall, it is just a handle for some previously obtained value.
That idea is more complex than it appears. Should the inferred type be
'List<String>', 'AbstractList<String>' or 'ArrayList<String>'?
I suspect you would say the last,
You suspected right, which is no surprise, as it is the only reasonable
choice in that particular context.
but really, is it so very, very bad to type
final List<String> myList = new ArrayList<>();
I find the direction of the inferral somewhat unlucky.
I'd rather infer the type from right(expression) to left(variable),
than the other way round. I guess that was discussed thoroughly
before it was introduced, so I might just miss knowing those perfect
arguments against my preferrence.
