Microbenchmark testing Python, Numba, Mojo, Dart, C/gcc, Rust, Go, JavaScript, C#, Java, Kotlin, Pascal, Ruby, Haskell performance in Mandelbrot set generation 

Benchmarking several languages/tools with Mandelbrot set generation. 1-to-1 translation of code from one language to another. No SIMD, no multithreading (except prange() trick with Numba), no tricks (e.g. skipping sqrt), a bare minimum of language specific adjustments to make the code nicer while keeping all loops and operations in place.
