It was my impression that the "current SpiderMonkey implementation is
nothing to get excited about in terms of performance" which made your
unfavourable comparison to CPython so puzzling (and does the tamarin
website actually show any performance comparisons with CPython?)

I guess Lisp is a safe-ish example but I don't think Self really made
it out of the lab, and it really depends which Smalltalk
implementation you have in mind and what you think about Pysco.
