Like Ruby!
Like ruby? AFAIK nothing new ever came out of ruby. It was just a nice pure implementation of smalltalk on top of Perl. Of course the everything is a method strategy and unoptimized MOP burned them.
Just look at their new jit. Can anybody think of a worse strategy to implement a jit? There are serious technical and management problems. V Makarov at least wrote the register machine before the naive cc -> so jit, but then the Japanese came and even ripped that out.
A curious definition. Not only Smalltalk is still used (e.g. in fintech), but it's intelectual virtues are always revisited and rediscovered by new generations who, invariably, try to come up with a "modern" version of it, or something inspired by it.
