unsupported to call class static array field

[LiaoPeng]

assemblyscript

class Container {
  static MONTHS_IN_YEAR: i32 = 12;
  static DAYS_IN_MONTH: i32[] = [31, 28, 31];
}
var months = Container.MONTHS_IN_YEAR;
var _days =  Container.DAYS_IN_MONTH[1];

Expected:
The expression var _days = Container.DAYS_IN_MONTH[1]; is ok.

In fact:

ERROR AS100: Operation not supported.
 var _days =  Container.DAYS_IN_MONTH[1];
