Unfortunately some time you want to do this - C# has "new" as well which
explicitly lets you do this (otherwise it's only a warning). If anything I
could see us providing a warning here but we'd need some way to squelch it
as well. And it would have an additional cost for constructing classes that
I'm not certain would be worth it.
