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 !

Good point.
We should definitely avoid confusion as much as possible, and avoid introducing ambiguities.

I think we should support only explicit array initilization with array type, that is "new int[] { 2 }" for compatibility's sake.

or we just support new int[] {1,2,3}  ?

What happens for def a = { 2 }, is it parsed as a closure or an array initializer?

Hi Andres,

       Parrot can parse ` def a = {1, 2, 3}` properly, but it can not parse
`{1, 2, 3}`, which is not supported by Java too.

       This is the initial implementation :)
