(Thoughts welcome.) Origin of bug. ------------------ When amsmath is loaded, the showkeys package patches it in two places to insert the equation label: `\maketag@@@` and `\tagform@`, which are called by...

I only half agree with Frank about his last paragraph: the combination of packages is unlikely to work but they don't really have conflicting goals. Using "multicol + footmisc with...

Probably also relevant in all other modules (e.g. `intexpr` could be changed to `int expr`). I have no opinion on whether to do that.

@RuixiZhang42 I haven't followed all of the discussions, but do you think these exact methods could be generalized to arbitrary units, even at a rather steep performance cost?

Ah, you have a good point, I had forgotten that the conversion to bp and the like is done with an exact ratio. Then I think you're right that we...

To keep most operations O(1), you can use a doubly linked list: let's say the prop is called `\l_my_prop` and it has keys `A`, `B`, `C` with values `Alice`, `Bob`,...

I'm starting to implement this, but only two implementation: standard implementation, and doubly-linked list. Can I use \expanded? It will make my life somewhat easier, but it is probably not...

I'm actively working on this, it requires a lot of small changes to the code, to make every function check correctly for which type of prop to work with. I...

For the record I just had the following idea to make `V`-type expansion work for these props as well (for use as items in other props/seq, cf #1067). Make these...

@josephwright It seems the main missing step was the code to check validity of a prop (in `\prop_show:N`), which is pretty tricky to do correctly. Also some further checking that...
