Is there a config file where I can set (read-decimal-as-inexact #f) to
be the default for the racket language whenever I run DrRacket?
I think someone answered this once before but I can't seem to find the
answer. I did try putting this command ~/.racketrc which works for
interactive mode for comm
Dear All, I am using Racket 5.1 on Windows.I have a program which renders an
OpenGL image into a bitmap. The following used to work inPLT-Scheme. (define a
(make-object bitmap% 100 100 #f))
(define b (new bitmap-dc% (bitmap a)))
(send b get-gl-context) Now it returns #f.Is it a bug or feature?Is
Yes, that's what I was looking for. Brilliant, thanks :-)

I know I've used this idiom, and even more:
(define-values (x y) (let () ...))

Yes, that is Racket style these days (as codified in the style guide).
Saving the level(s) of indention is great, as far as I'm concerned.
As to the original question, tho, it seems like you can usually just
put the nested defines next to the original define and unless you have
a very big function
Is this "let over lambda", instead as "define over lambda"?
Actually in general, is the intent that define should be an
alternative to let in all cases? Although you pay 2X typing the
symbol itself, you save parens and a level of indent? :)

The grammar for define includes
(define id expr)
but I wonder if this couldn't be relaxed to
(define id body)
so that you could write things like
(define count
(define i 0)
(λ () (begin0 i (set! i (add1 i)

I'm struggling to get to grips with the API: how do you extract the details of

At the moment I have a shadow module of test-cases for each actual module. I'm
trying to unify these so that one procedure will run all the tests and bring
