No, there are still some repl bits of boot-9 that need limning. I skipped over some parts when revising boot-9 recently, and hope to come back to them soonish. > What about single-stepping Should be possible, given source line info and the next-instruction hook. > and expression-level debugging? Trickier, we'll need expression-level debug info in the procedure. And which expressions, the expanded ones or the ones from the original source? I think I'd need to spend some times with other schemes to figure this out. Breakpoints would be good too. Andy -- http://wingolog.org/
