Thanks. So you're saying that ERR5RS mode supports syntax-case macros? How do I enable it? The following doesn't work: $ larceny -err5rs -- stripped-randomwalk.scm -e "(define pp pretty-print)" -e "(main 10)" -e "(quit)" Larceny v0.97a4 (alpha test) (Mar 13 2009 15:30:01, precise:Linux:unified) ERROR detected during macro expansion: Malformed syntax-rules (lambda (stx) (syntax-case stx () --- > -Felix > > [1] William D Clinger, "Hygienic macros through explicit renaming."
