Well I could have sworn I got the error to happen last night in plain racket. Apparently I was debugging too many things, too long, and got confused. 1. I get the same result as you with plain racket 6.2: $ racket sub.rkt 42 42 42 42 2. The error comes with using errortrace: $ racket -l errortrace -t sub.rkt 42 42 x: undefined; cannot reference an identifier before its definition in module: (submod "/tmp/sub.rkt" sub/module*/#f) errortrace...: /tmp/sub.rkt:8:2: (eval (quote x) ns) /tmp/sub.rkt:22:0: (eval-x-in-submodule-namespace (quote-module-path sub/module*/#f)) context...: /tmp/sub.rkt: [running body] 3. Unlike you I do also get the error in DrRacket -- even with the Language settings at "No debugging or profiling" [which IIUC ~= no errortrace], "Preserve stracktrace" off, and "Enforce constants" on: Welcome to DrRacket, version 6.2 [3m]. Language: racket/base [custom]; memory limit: 128 MB. 42 42 x: undefined; cannot reference an identifier before its definition -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
