So, while I totally understand Frank’s point, I’m less worried than
he is, and use Flex’s C++ backend.

It seems that the resources developments of Flex are scarce.  They
easily agree on issues, but even for the most trivial ones (e.g.,
delete three lines, https://github.com/westes/flex/issues/379),
they ask for a patch.

But, then, who am I to discuss about the maintenance resources :-(
