Поиском не нашел. ИМХО, вещь интересная.

In my Finding Things chapter of Beautiful Code, the first complete program is a little Ruby script that reads the ongoing Apache logfile and figures out which articles have been fetched the most. It’s a classic example of the culture, born in Awk, perfected in Perl, of getting useful work done by combining regular expressions and hash tables. I want to figure out how to write an equivalent program that runs fast on modern CPUs with low clock rates but many cores; this is the Wide Finder project. (с) Tim Bray

Замечу одно: Python оказался быстрее Erlang'а в 600(!) раз.
