Thanks Life!

I had a chuckle when you called Vimscript a "sane language". I'm more
of a Lua or Python or C guy myself. But looking at your code, it looks
like the Vim9 script language is a big improvement over that old viml
stuff.

Anyway, could you please summarize what you see as the benefits of
reactive programming? As a guy who has used a lot of callback routines
(C, Perl and Python) in his life, I kinda sorta maybe understand at a
gut level, but I don't really fully understand the benefits in a way I
could explain or use them.

Thanks again for this ultra-cool post!
