Disappointed/surprised `Fortran` does significantly worse than C...

Edit: ok, the benchmarks are not only scientific computational ones. For the latter, Fortran still acts very well...

Yeah, he mentions that as a caveat that all the benchmarks are done using own language scripting abilities... no external functions are called.

And indeed, you're right to highlight that no self-respecting python coder won't use efficient external 

 libraries to do the computationally heavy matrix operations.

And indeed, you're right to highlight that no self-respecting python coder won't use efficient external `lapack` or `arpack` libraries to do the computationally heavy matrix operations. `numpy` is nearly fully `C`-code under the hood with some `C++` as well.
