I just got around to watching Avi Bryant’s talk on MagLev, a new Ruby VM built on top of GemStone’s Smalltalk VM.

Presumably this is the kind of thing Smalltalkers have been able to do for decades, but to me the prospect of having this kind of freedom on a Ruby platform is very exciting. Terrific stuff. I wonder what performance is like.
