Benchmarking a number of languages on the same task - mandelbrot.
Task is to generate a 5000x5000 mandelbrot and write the result to a text file (gnuplot matrix).

Time is in seconds - on a Macbook M1 (8 cores). All times include file I/O.

Just learned enough about generics to create a test double for my search engine!
