Subject: bug#7825: Cannot return from the debugger
Date: Tue, 11 Jan 2011 16:32:00 -0500

Package: Emacs
Version: 24.0.50

The limitation that we "Cannot return from the debugger in an error",
is a bug: we should be able to continue (i.e. run the code of the
corresponding error handler), just as if the debugger had not been invoked.
