Hi Folks, As already discussed a few months ago [1], I've started to move some *.src files to C++, based on the idea that the custom template engine of Numpy is very similar to C++ templates. This is a short update on the on-going translation. I've already converted the following sources: - selection.c.src - mergesort.c.src - heapsort.c.src - timsort.c.src - binsearch.c.src - clip.c.src - radixsort.c.src One can get an idea of the conversion work through these two PRs: - A typical conversion: https://github.com/numpy/numpy/pull/20897 - C/C++ layer: https://github.com/numpy/numpy/pull/20968 (this is probably the most technical part) I've also submitted this work for a Small Development Grant to NumFOCUS. I'm planning to finish the conversion whatever the result, but that would still be great ;-) See ++ Serge [1] https://mail.python.org/archives/list/numpy-discussion@python.org/thread/BLC...
