I think I was being mislead by what might be behavior from DrRacket's 5.1.1's printing of syntax objects. When I introduce displaylns to let me explore the structure of the syntaxes, as in: ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; #lang racket (define x (datum->syntax #f 'hello (list 'my-source 3 3 18 5))) (define y (datum->syntax #f 'world (list 'my-source 3 9 24 5))) (define a-bigger-syntax #`(module foo racket/base (#%module-begin #,x #,y))) (define a-reconstructed-syntax (syntax-case a-bigger-syntax () [(module name language (a-modbeg body ...)) #'(module name language (a-modbeg body ...))])) (displayln a-bigger-syntax) (displayln a-reconstructed-syntax) ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; then under DrRacket's syntax printer, if I click on the 'hello identifier of the snip representation for a-bigger-syntax, I can observe that it's at position 18, line 3, column 3, and span 5. That's what I expect, because I built the syntax object that way. But if I click on the 'hello identifier of the a-reconstructed-syntax graphical snip, the snip reports itself as being at position 358, line 8, column 28, with a span of 19, which is not correct. So something strange is happening here. _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
