Hi Anton

please don't worry. I really appreciate all your hard work. I got a
little carried away, I'm sorry.

exactly. The quick migration which I have done yesterday passes the
tests, and seems to work at first glance, but there were some tricky
sections of the code. Which I converted but I didn't test. I feel more
comfortable with old and well tested boost::python version.
Also I see that Vaclav has done this already [1]

this is clear.

Thank you! :))


Another note: I just realized that the compilation benchmarks might
have not been fair, because I think that I added few more
registrations (like Vector2c, or sth. like that) while doing pybind
migration. I will compare again without these extra registrations.


Another comparison note:

8. boost::python is much more picky about the order of registered
   functions, and sometimes does not work if the order is "wrong".
   pybind always resolves the function overloads correctly.


best regards
