ca 1/3 & 1/8 on time & space - quite an improvement! Well done!

I’d forgotten that this day was also pretty hard. My “unpack” function (snap!)
also delivered the goods for both parts. It works through the message calling
either “literal” or “operator”. literal is self-contained, returning a value
and an unused message fragment, while operator calls unpack
Mine is recursive: parse calls operator, and operator calls parse.
That's why I added a trace mechanism (an echo statement showing the
string I used to represent what would happen to the value, along with
the value itself, for each packet) -- so that I could visualize what
was happening.
By the w
So your parse is akin to my unpack.
I was going to say that my "operator" and "literal" were both dyadic
too, but checked,
and now find I'm wrong. But "unpack" itself is indeed dyadic; irs

I have gone back and improved the code a bit for day 22 part 2 - well,
quite a lot.
Part 2 is now solved in ~1 second in ~ 6.5 MB ! (It was 30-60x slower
and perhaps
1500x more space-consuming.)
Will comment more when Raul presents his comments next week.

Wait til you get to 24. That one was the most difficult for me. It's not
really about programming, more like an old-fashioned logic puzzle.

Personally, I have yet to solve 24. I'm still working on the second half of 23.

First half of 23 for me - haven’t seen the light yet!

Day 17's puzzle was a change of pace from previous puzzles. Instead of
a multiline chunk of text representing the puzzle, we got a single
line, which looked like this:
target area: x=20..30, y=-10..-5
All that would vary would be the numbers.
