Racket doesn't implement hash tables using a hash function. If I
recall correctly, it uses b-trees as the representation for a hash
table. The Racket reference states that "Immutable hash tables
actually provide O(log N) access and update. Since N is limited by the
address space so that log N is
Racket allows different types of keys in a single hash, so there must be a
hash function that works for different types(different primitive types), I
wonder how Racket implements this under the hood.

I don't mind the parentheses. But I think Racket is kind of bloated and
fragmented (I'm new to Racket, but this is the impression that I got so
far). There are a lot of forms that are doing similar but slightly
different things (e.g., the many let forms), and features that are not well

I’m probably wrong but the thing that is keeping me
I will mention that there is a Racket kernel for Jupyter. I use Jupyter
notebooks a great deal for teaching, but haven’t used the Racket kernel beyond
installing it and basic testing.
Anyone have experience with using Racket with Jupyter?

Hi,
I’ve just posted a DrRacket2 issue on the RFC’s github

My first suggestion is a 'notebook mode' like Jupyter notebooks.
FYI did you

This is certainly confusing.
The missing piece of the puzzle has to do with expansion in an
immediate module body. In that context, the macro expander adds the
module's "inside-edge" scope (unshifted) to the result of any macro
expansion. So, the expander is adding back the inside-edge scope that

On the topic of making Racket 2 more appealing to new users. As a new user
myself, I have one (likely uninformed) suggestion:
Design and promote a "boring core subset" that an experienced programmer
can pick up easily and be as productive as when using an "ordinary
programming language",
