Also note that in Java Integer[] o = { 3 }; and int[] o = { 3 }; both work but Object o = { 3 }; does not compile because the syntax '{' '}' with no explicit array type do inference (and here Object is not an array so the inference fails).
Supporting only explicit array initialization seems to be the right choice !
