    Hi,

I'm having some problems using the List class in InterViews 3.1 beta3.
In IV3.0 the following worked fine (simplified example):

 1  class Block
 2  {
 3      public:
 4          int f();
 5      private:
 6          int n;
 7  };
 8
 9  declareList(BlockList,Block*);
10  implementList(BlockList,Block*);


But with IV3.1 the compiler (Sun CC 2.1) complains with the following
message:

... line 10: error: no standard conversion of  const struct Block * to  
                    struct Block *

Probably because the insert function of List is declared to accept
a const T&, which in the body of insert is put in the array of T&'s 
(which are non-const).

An ugly workaround is to define the list like this:
    declareList(BlockList,const Block*);
    implementList(BlockList,const Block*);
And to cast the const away from list->item(i) whenever needed.
This also produces some (6) warnings of "two const declarators",
like in BlockList::insert( long, const const Block * ).

Is this a bug in List or am I missing something?

Thanks for any help on this matter.
