How can we allow using phobos with asserts/contracts?

FYI, solidstate figured this out. It was because of an out-of-bounds 
index on `BitArray`.

But that irks me. Why wouldn't `BitArray` do a bounds check? And then I 
remembered -- Phobos is built in release mode even when your app is not.

I literally *cannot* request from the compiler that `BitArray` enforce 
its contracts without rebuilding the library completely. I never want to 
build code that doesn't have bounds checks.

How can we fix this?
