I should clarify:

I think idup should fail if the element has any *non-immutable* references in
it.

Note this leaves us with no ways to dup a const array with references in it! 
Should we have cdup?  A workaround to both would be to always allow dup when an
explicit cast is involved.

i.e.:

auto arg2 = cast(const(C)[])arg.dup;
