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. Best regards, Mikael
