Now I am trying to include Alexis's data/collection as defaults. Thus I need to:

I am somewhat reluctant to use structures as I want to keep the interpreter as
minimal as possible. Also, I'm not familiar enough with the semantics of frames
to implement it in interpreter.rkt.
With regards to mcons being different from cons, Oscar Lopez has suggested that

There was an issue with the signatures on the Windows installers for 6.9.
We've uploaded new, properly signed Windows installers to

Thanks to Magda Wojciecchowska for the report!

Hi Brendan,
I'm wondering if you tried the here string syntax for your use case,
which other than the fact that it requires a couple of newlines seems
similar in vein to what you were going for (e.g. it doesn't escape
anything)?

I wrote a little Racket meta-language that adds a dispatch macro to the
readtable for typing string literals without escape characters. You start with
two or more #'s followed by any non-# character, then the actual string
content, then end with the same non-# character and the same number of #'
Does anyone have advice on how to debug scope-manipulating meta-programs?
I'm not talking about the little 5 line example macros shown in the docs, but
thousands of lines of
meta-programming that intentionally manipulates binding, but sometimes
apparently does it wrong.

I hope this helps

I've been trying to write a Racket interpreter that can interpret itself.
interpreter.rkt contains the code for the interpreter. It is pretty

Hi Philip,
I don't have an answer to your problem, but I'm curious as to what do you store
in "local.rkt" and "production.rkt" to justify such a complicated solution.
In the projects that I worked on (Racket or otherwise), local vs production
differ in the values for different parameters, which
