Porting java code I incidentally stuck with such an easy and stupid problem.

Java uses Object variable as 'universal type' for storing 'everything
(although it's not a typesafe).
How legally to assign variable value of some type to the Object variable in
D?

Something like on java:
-------------
 Object [] table = new Object[n];
 String key = "some key";
 table [0] = key; // legal code
...
and vice versa
------------

But for D I stuck:
...
   Object[] obj = new Object[10];
   wchar[] str = "fff";
   obj[0] = cast(Object)str; // error: cannot cast from wchar[] to Object

What's I make wrong?

D strings don't subclass Object. What else is being stored in "table"? Is it
storing key-value pairs? If so I'd consider using an associative array
indexed by wchar[] and declared as Object[wchar[]].

It's a DWT code. Something like storing and 'playing' with string key-value
but I need time to clarify it. I hoped to run this place fast but now see it
will take a time.

 If so I'd consider using an associative array
 indexed by wchar[] and declared as Object[wchar[]].

Thanks for all responds. I'll try some way.
