Hello, there is a write-circle/read inconsistency, see attachment. I tried patching the reader with code from srfi-38, but that is not straightforward: there is a letrec-based recursive call to read further tokens, whereas bigloo is grammar-based. Maybe this example can be adopted as a testcase for R7RS support at some point. Cheers, Andreas
