Here are two syntax errors that behave differently in DrRacket: #lang racket
(define-syntax (m-late stx) #'(let () (define x 0))) (define-syntax (m-early stx) #'(let-syntax () (define x 0))) ; (m-late) ; (m-early) DrRacket *correctly* highlights the source location of the errors in both cases. Additionally, for (m-early) I can click on the X button to jump to the error location. However, for (m-late) the X button brings me to internal Racket code. What's going on here? In case it helps, here are the error messages when I run the code in terminal: ;; m-late errstx.rkt:4:4: begin (possibly implicit): no expression after a sequence of internal definitions in: (begin (define x 0)) location...: /Volumes/ramdisk/errstx.rkt:4:4 /Volumes/ramdisk/errstx.rkt:4:12 ;; m-early <collects>/racket/private/letstx-scheme.rkt:38:17: begin (possibly implicit): no expression after a sequence of internal definitions in: (begin (define x 0)) location...: <collects>/racket/private/letstx-scheme.rkt:38:17 /Volumes/ramdisk/errstx.rkt:6:19 -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
