Thanks for your reply,
I think I prefer the latter approach.

I've got a macro that extends function definition by letting the user rebind
some identifiers with different values, which are then only available in a
certain context. For the sake of simplicity suppose it looks like this:
(define/foo (func v ...)
#:bind [helper1 expr]
#:bind [helper2 other

I believe box-immutable isn't what you're looking for, or would be too obvious
an answer?

Ok, by using `syntax-debug-info` I was able to get somewhere. However, I want
to make the variables I'm putting into the namespace all immutable. For that I
thought I could use `define-syntax` within `eval`, but `define-syntax` appears
to not have any effect:
#lang racket/base
(require (for-syn
Hi I want to do something like this:
(define test "(1,2,3)(4,5,6)(7,8,9)")
(define (convert m)
(for/list ([i (cdr m)])
(string->number i)))
(regexp-match* #rx"([^,\\(\\)]*),([^,\\(\\)]),([^,\\(\\)])" test #:match-select
convert)
But that fails because the matches are represented as pairs
10 matches
