Also note that in Java
&= nbsp; Integer[] o =3D  { 3 }; and int[] o =3D  { 3 };
both work but
  Object o =3D  { 3 };
does not compile because the syntax '{' '}' w= ith 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 in= troducing ambiguities.

What happens for def a =3D { 2 }, is it parsed as a closur= e or an array initializer?

Hi Andres,

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

       This is the initial implementation :)
