AFAIK. Yeah, that's exactly what I meant by "the details escape me now". ;-) `display-backtrace', for instance, knows how to do this, but it gets the source from the frame (rather than from the procedure). Apparently, we can't do this with `procedure-source' because it does many things (including unmemoizing and returning a fresh expression if needed) that remove source properties. We might be able to change this using some Smart Tricks that escape me currently. ;-) Thanks, Ludovic. _______________________________________________ Guile-user mailing list Guile-user@gnu.org http://lists.gnu.org/mailman/listinfo/guile-user
