Vectors allow manual inheritance (more or less the way a compiling
object system does it): if a superclass defines an N-slot vector,
subclass slots start at N+1. A cast to super just changes the first slot
(type identifier) - superclass methods already ignore all slots beyond N.

Guessing: they compile to identical operations - block-set! etc in lolevel.
