To support the new debugger, all that is needed is a way to distinguish whether one entered the debugger as a result of an error (so that one's interested in the current frame) or because of a breakpoint (and then the relevant source info corresponds to the _next_ frame). I think Andy's planning to make that information easily available at some point, and i was waiting for that to add full support to Guile's debugger in geiser (including things like setting a breakpoint in the current line/function &c.). (I'm just being a little lazy, because i know it's already probably possible to snarf that information from the repl object, but it's a bit convoluted.) Cheers, meister jao -- I want to stay as close to the edge as I can without going over. Out on the edge you see all kinds of things you can't see from the center. -Kurt Vonnegut, Jr.
