I also have to use a modern C++ environment, which before was
optional.  Personally I don't care, I'm not developing a portable
application in this case.  People who do are in trouble now.

Hm...  I understand what you mean here, and it might be the case

There is the TODO list for instance.

Fair enough.

That remains a Free Software project.  I'd like to be paid to work on
it, but it isn't the case.

OK, if you want a project, then there is one thing we need: that
someone find a good implementation of bit vector to implement sets.
We need a good implementation, efficient and with a nice interface.
There is a crucial need in Bison, but for the time being, unions,
intersections etc. are computed but loops all over the place.  We need
macros/routines that raise the abstraction level up to sets.
