(We probably need to support some other form of continuation barriers that allow local escapes -- as per http://thread.gmane.org/gmane.lisp.scheme.plt/40465 -- but that's another issue.) Anyway it is possible to do an escape from a continuation barrier with an abort to a prompt, I think. That should be fixed. _______________________________________________________ Reply to this item at: _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
