cannot use polymorphism via array.

dmd complains..

test.d: function test.foo (Interface []array)
does not match argument types (Class [5])
test.d: cannot implicitly convert expression
classes of type Class [5] to Interface []

to the following code.

<code>
interface Interface {}
class Class : Interface {}
unittest
{
void foo(Interface[] array) {}
Class[5] classes;
foo(classes);
}
</code>

which does work on Java, btw.
