Link for “automatic differentiation” topic: Automatic differentiation of Fortran code, opinions?
And I would also like to (briefly) discuss the “goal of Fortran”, link: High Performance Fortran (HPF) history and lessons
Also I would like to show “conditional expressions” prototype in LFortran, link: https://github.com/j3-fortran/fortran_proposals/issues/183#issuecomment-707498368, showing a demo how it works (5 min)
