Mostly to be able to construct classes in places other than GC managed 
memory.  Memory mapped files for example, fixed-size arrays within GCed 
classes, stack-based arrays, etc.  Some of these can be accomplied using 
.classinfo.init.sizeof or whatever, but others require the size to be 
known at compile-time.
