[chuck-users] a few language questions

[Michael Heuer]

A couple more:

If an array is defined but not instantiated with a capacity

Object @ values[];

should it be possible to instantiate it later with a capacity of nulls?

Object @ [100] @=> values[];


How about a cast?

class MyEvent extends Event
{
  int value;
}

fun void handleEvent(Event event)
{
  <<< ((MyEvent) event).value >>>;
}

Thanks,

   michael
