Ok.

I've posted a comment to the commit, and will study the issue further.

There is not. I think you should add something into your documentation that says
"Run racket -e '(require laurent/init)'"
after installing. In my mind, this was not an oversight in the design,
but a purposeful thing.

Don't feel lonely. Keep putting your stuff in github. Update your
readme, put in some examples, maybe in a submodule as unit tests:

The intent of the "mywbr" span is to allow a line break between "/" and
the following character (since we sometimes have long identifiers where
characters like "/" are a helpful break point). The "mywbr" style sets
the span width to 0 to avoid rendering any space.

Umm, ok.
I retract my comment.
I had not inferred that from the.docs.

Is there something similar to the `install-collection' field in info.rkt
but for package installation instead of collection installation?
In particular, I'd like to run some interaction with the user to create
some default files.

I know about the macro stepper and it doesn't work for my use case. I
don't have a simple macro, I have the entire TR typechecker/optimizer.
Thus splitting it out into its own module is not feasible. Also
because of how TR works there is one major macro application and the
macro stepper cannot see

Thank you all. Your examples are really surprising to me.

The competition does it better, see Python's fsum:
