I thought D was supposed to automatically infer the most derived common
base class to assign to an array literal of different types? At least,
that's the impression I got from TDPL.

What am I doing wrong?

I have no idea (and haven't read TDPL), but adding a new A somewhere in  
the array makes it work. Compiler bug..?
