Is the inability to use dup and ~ with const arrays of class objects a

It has to be. There is no cdup.
For any const(T)[] x, the type of x.dup is T[]. Because this would mean
that you would remove const, you cannot do that. Nor can you idup, since
implicit conversion to immutable is not possible.
As far as I know, ~ works with const arrays of class objects. Can you
give a case where it fails?
