Description

Object[] a = [1]

this currently throws an exception at run time.

It would be convenient if it caused toArray to be called on the List

I think this is bad, if you need Object[] you should do something like

Object[] a = new Object[]

{ 1, 2, 3 }

People rarely use arrays.

we decided to make this possible for the new parser. So legal methods of declaring arrays are:

a = [1,2,3] as Object[]

or

Object[] a = [1,2,3]

of course, the last one allows the "as array" syntax too
