Well, I know that the game will run only on Gnu/Linux systems. A
alternative that I see is using ffi to provide 1 function that returns this
number but if exists some racket-only solution I think is better, right?

Well, call/cc is like (in racket) delimited continuation, and have a
implicit prompt around a s-exp, so, as begin is a macro, he don't create a
prompt. The continuation captured is (+ 1 []) in your example.
If you change the begin to a let, this works, because let expand to a
application of a lamb
to handle this special
case too. The repository is racket-peg on GitHub, from user rain-1. There's
a issue about empty string in the second place I think if this helps.
Thank you for the attention. :)

Hi. I am contributing in a library that create functions to parse
PEG(parsing expression grammar). To implement a feature, I need to know the
return's type of a function. We are using racket, not typed-racket, so I
think that I need to get the contract or something like that. I dont see in

Hello everyone,
I am trying to use a set of bindings to SDL2 and I am at loss on how to use C
unions.
If I understood correctly both make-union-type and _union procedures create a
new ctype; but how do you actually create instances of these unions?
Thank you for your attention.

Does that mean that lambda expressions have an implicit (begin …) block in them?
(begin ((displayln 1) (displayln 2) (displayln 3))) leads to an error
(begin . ((displayln 1) (displayln 2) (displayln 3))) displays to 1 2 3
Thank you for the detailed explanation I think I get it now.

Hello everyone,
Since I've discovered the concept of metaprogramming I've been quite interested
in Racket and its syntax extension capabilities.
While searching for a memoization syntax extension I found a macro whose
pattern extension remained unclear.

Using Scribble, how can I use @interaction to document examples in
different languages?
I have noticed the example for Typed Racket on chapter "4.5 Evaluation and
Examples", but is there a way to use @interaction or a similar Scribble
function with a language with a custom reader?

Is this how it is usually done? For example, does my browser (firefox)
