Hey Cem.
I went through the draft proposal and had some questions.
Which direction do you think I should pursue? I am more inclined towards
refactoring the enitre data_frame because if I believe correctly uBlas is
moving towards C++20. Should I stick with ETs or can I use Ranges and
Concepts?
I was thinking to stick to standard C++20 Ranges only instead of Eric
Neibler's One Ranges v3 library considering std to be more relevant.
