Right, although it is, in fact, @slot-ref which is the special form (I
said "@assert-bound-ref" by mistake).  Try the same benchmark
accessing the third or fourth slot.

Regarding Guile vs Python: Python is byte-compiled.  We once had a
byte-compiler "guile-vm" which could have been merged into Guile.
Maybe it's still possible with some work.
