It makes it impossible to do dynamic casts on class instances with AliasThis.
It needs to be changed regardless of whether it's intended or not.

It also makes it impossible to cast some class references to void* while using
AliasThis, another important conversion. A workaround for this might be using a
union, but I don't think there's a workaround for the dynamic cast.

opCast cannot do the work of these in-built casts.
