Is it 'wrong' to add a disappeared-use property onto a syntax object
even if the use wasn't actually disappeared? Its not very obvious what
semantics these syntax properties are supposed to have.
The situation I'm in is that the code that determines examines the

Right now im teaching a boy how to program in racket,
i know a that every programmer needs to understand some basic english, but
its hard for a teenager to learn english and programming at the same time.

I think it would make sense to add an option to `scribble/doclang2'
(and `scribble/doclang') to replace `decode'. I've added that to my
to-do list, in case no one gets to it first.

Probably because the indicies have to be rebuilt after any documentation
changes; you're seeing messages that say something about that rebuilding
process, I believe.

the dev@ list) so there may be something else going on t
Yes, agreed. It isn't a good situation.
There are a lot of things resting on just one man's shoulders around here,
however, so if anyone has the energy to try to take this on and sort out
what's needed, that would be wonderful.

I've created a mini-collection out on Github.
https://github.com/RayRacine/tlib.git
Consider the single collection, c1, with 4 modules.
m1.rkt -> m1a.rkt -> m1aa.rkt
m2.rkt
Where m1 depends on m1a, m1a on m1aa and m2 had no dependencies.

I like an idea of setting breakpoint and when it is reached during runtime

one of the Schemes (Gambit?). I tried, but I couldn't make anything similar

I thought that the syntax-parameter approach with macros would add
complexity to functions with optional and/or keyword arguments. But your
solution with parameterizing over the state and then the functions solves
my problem completely.
Thanks for sharing this excellent solution!
On Tue,
I have several decent sized collections, each utilized via a 'raco link -d
/a/b'. I end up doing numerous 'raco setup x' after munging around in a
particular collection set.
A typical stdout from a 'raco setup' always appears to have "mystery"
collection entailment to vary degrees over time. e.g

Most of the time, you won't need all the features of the struct.
For pointers you don't care about, you can simply use the generic _pointer
type, as long as you don't use the /types/ behind that pointer.
Note that you can still use the pointer itself though, e.g., to pass it
around functions.
