Hello, Arsen.

A short progress report.

I apologise for not having been as fast over the last few days.  Partly,
I'm bringing up a new computer, which never goes as fast as one would
like.

But mainly I'm struggling with the unfathomable complexity of C++ lambda
functions, as documented on
https://en.cppreference.com/w/cpp/language/lambda.

In my not so humble opinion, the C++ standards people have completely
lost the plot.  The number of special cases in just the syntax,
apparently just to save a few characters from a program's text, has got
beyond the point where anybody can grasp it.  Nobody in this group of
people appears to be able to say "STOP!", though somebody sorely needs
to.  I dread to think what will be coming out in C++26.  :-(

Anyhow, I've spent all afternoon on the problem so far, and I think I can
see my way to a solution.  It will still take a few more days yet, I'm
afraid.
