Hi, I'm developing a bunch of packages using Snow and Gambit and really need some help with debugging. I am using generic Snow scripts as defined in the documentation. Is there some way of using an interactive prompt (at this point I have quite a lot of interdependent packages if that makes any difference)? Alternatively, is there some way to enable stack traces? Or anything similar? For example, at the moment I see: qp6 lines: SNOW_TEST="lines-base" ./lines-base.scm *** ERROR IN #<procedure #2>, "../../../pkg/gambc-4.0b22/4.0b22/syntax-case.scm"@9169.1 -- no expressions in body (lambda (#(#(source1) first "/home/andrew/projects/personal/src/scheme/lines... and I have no idea what part of my code that might be related to. I probably just need to be pointed at the appropriate documentation - I looked on the Snow site, but it seems to imply that I need to read a Gambit-specific section that doesn't exist(?). Thanks! Andrew
