I hope readers won't get bothered by what is mostly a link to blogpost
(well, two of them :-)), but I suspect there at least 2 or 3 people
who might be interested in the following analysis:

http://www.corsix.org/content/micro-optimisations-can-speed-up-cpython
Interesting articles, thank you. I wonder why the author doesn't propose
his patches for CPython. Does he fear that CPython can become faster
than Lua? ;-)
And the following article should be especially interesting for Victor:

The part of optimizations already are applied in 3.6 and 3.7, but `a +
b` still is slower than `a.__add__(b)`.
See https://bugs.python.org/issue30509. All optimizations already are
applied in 3.7 by Victor. In these microbenchmarks 3.7 is much faster
than 2.7 and 3.5. But still there is some overhead due to excess
intermediate levels.
