@ldionne @Mordante now that all of our supported compilers support concepts, we can revisit this patch. What's your general appetite for using concepts (here and elsewhere for C++20-or-later code)? I prefer concepts, but I think Arthur had a benchmark showing `enable_if` was quicker to compile IIRC.
