Before this thread, I thought the progress of F18 was much further
than it is. My initial comments assumed it.
Now, I am surprised it's not using LLVM API yet (a clear and
consistent complaint of the previous one), as well as having its own
driver, test infra, etc.
The lack of C++ compatibility may look small now, but once we want to
move to a newer standard, Flang will be the bottleneck. In a monorepo,
these things are even more important.
F18 was supposed to be a whole new front-end, from scratch, but it
looks to have carried along many of the previous projects' flaws.
I really wouldn't like to see the next release with such wide range of
So, +1 to both waiting the release branch as well as a concrete plan
with a deadline to address all the critical issues before the next
