A. I just [re?]discovered Seed7 language, one of the few languages with multiple dispatch, also extensible (not though macros).
https://groups.google.com/forum/#!topic/comp.programming/_C08U8t4dRg "Seed7 has more then 90 libraries now." [in 2013, after 7 years] They hit Top100 (93? top) on TIOBE, but nowhere to be found now. They seem very similar, except for Pascal like syntax, I guess there must be more to it.. B. Chapel can be faster than Go or competitive, but also much slower (is a parallel language, not sure if not working/meant to work always..): http://benchmarksgame.alioth.debian.org/u64q/chapel.html fasta <http://benchmarksgame.alioth.debian.org/u64q/performance.php?test=fasta> source secs KB gz cpu cpu load Chapel <http://benchmarksgame.alioth.debian.org/u64q/program.php?test=fasta&lang=chapel&id=1> 20.59 28,868 1216 20.59 100% 0% 0% 1% Go <http://benchmarksgame.alioth.debian.org/u64q/program.php?test=fasta&lang=go&id=3> 1.97
