Details:

In CVX I make heavy use of class functions, stored in directories beginning
with '@'. These directories are not intended to be in the path, but are
visible if their *subdirectories* are.

However, the debugging facility cannot seem to handle them. If I type


dbstop @cvx/norm.m


I get the error: "error: add_breakpoint: unable to find the requested
function". If I then do 


edit @cvx/norm.m


The file is loaded into the GUI editor (indicating that it is, indeed, seen on
the path). If I then attempt to enable a breakpoint using the GUI, I get the
following modal:


The file
/Users/mcgrant/Projects/CVX/trunk/builtins/@cvx/norm.m does
not exist in the load path. To debug the function you are editing,
you must either change to the directory
/Users/mcgrant/Projects/CVX/trunk/builtins/@cvx or add that
directory to the load path.


Of course, I cannot do either if I want the code to work properly, because
many of these functions overload built-in Octave functions, and would now
shadow them. So it would seem that it is impossible to set a breakpoint inside
a class function.
